I'm curious to try out Amazon Q as part of Positron
I have this for the last part. What should I do ? % vi ~/.bash_profile ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ "~/.bash_profile" [New]
Is there a similar way to debug from a specific row onwards like we do with RStudio's red-dot breakpoints to the side of the scripts? Thanks.
Breakpoints are not available yet. You can create a similar experience by placing above the line of code you wanted to explore by typing: browser() So, if we had: f <- function(x, y) { z <- x + 1 browser() a <- z + y return(a) } f(1, 2) The debugger would be engaged after the function was called and its first statement was executed.
Thanks for this great tutorial. I like the layout of Positron IDE. I use Rstudio and most of my scripts are .rmd file. I have tried to run these scripts in Positron but always get an error. Does Positron support Rmarkdpwn files? If yes, how can I run all my code and get figures plotted as they are displayed in Rstudio? Note: I have the latest Positron and Quarto Extension is installed. You can recommend some tutorials too.
R Markdown support for Quarto is a bit iffy at the moment. I should have a video or two in another week or so.
I created the same app.R file on my desktop. When I try to run the file with the option 'Run Shiny App', I get this error 'Could Not find R. R is installed on your system? If R is installed, please make sure your PATH environment variable is configured correctly'. The same app works perfectly in Rstudio when I use 'Run app'. Did you maybe set something different during the Positron installation? Thanks
When you go to the selector in the top right, is Positron able to find your R installation? There's been a few issues with the R installation path being detected on Windows. I would check out: github.com/posit-dev/positron/discussions/3677
@@thecoatlessprofessor7674 Hi, thank you for your quick response. Yes, I selected R 4.4.1 but if I run the app using the the option 'Run Shiny App', I get the error I previously mentioned. Instead, if I run step by step the code using the option 'Source R file', the app works. R is regurarly recognized by Positron, because I am also able to run R scripts or quarto scripts. I have just problems when I try to run a shiny app (both single file and splitted files ui.R - server.R) using directly the option 'Run Shiny App'
Solved!. I re-installed R 4.4.1 on my laptop without modifying the default library where packages are stored (C:\Users\<my_user>\AppData\Local\R\win-library\4.4) and now the shiny app works perfectly using directly the option 'Run Shiny App'. In my previous R installation I changed the .libPaths variable to store all packages elsewhere and this caused the error in Positron
@@alessandrosperanza3909 Ahh! Thanks for reporting back. Glad to hear everything is working.
I'm relatively new to programming so pardon the basic question - I'm trying to run .rmd files in Positron (files created and run in VSCode & Rstudio just fine), but cannot. I'm seeing in Output a warning of "Warning: rPackageTask tasks are unavailable in the current environment." Edit to add Terminal output: rmarkdown::render(g:\\My Drive\\Graduate\\2024-SU-MGT6203\\3. MGT6203_Exams\\final.Rmd) Error: unexpected '\\' in "rmarkdown::render(g:\\" Execution halted * The terminal process "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command & 'C:\Program Files\R\R-4.4.1\bin\x64\R.exe' -e 'rmarkdown::render("g:\\My Drive\\Graduate\\2024-SU-MGT6203\\3. MGT6203_Exams\\final.Rmd")'" terminated with exit code: 1. * Terminal will be reused by tasks, press any key to close it." Googling has not produced solutions. Do you have any insights?
That's a bit odd. What happens when you try to use RStudio to render the same file? A couple of thoughts off the top of my head: 1. Do you have Quarto installed on your system? And are you using the latest version of Positron? quarto.org/docs/download/ 2. Can you move the document onto your Desktop? Off of `My Drive`? 3. Can you remove the space and period inside of the file path? e.g. `3. MGT6203_Exams` goes to `3_MGT6203_Exams`?
@@thecoatlessprofessor7674 Thank you for your reply! 0. The same file is rendered normally in RStudio 1. I do not have Quarto installed - I figured RStudio, VSCode, and now Positron should be more than enough. Do I need Quarto to run Positron smoothly? 2. I tried to run the file after moving it to Desktop, same Warning in Output and error message in Terminal 3. I tried this, same issue
@@anhc3440 You need to ensure that Quarto is installed in order to render an Rmd document in Positron. Please make sure you have the latest version of Positron to have access to the Quarto Extension.
@@thecoatlessprofessor7674 installing Quarto was part of the solution! Thank you!! Order of events: installed Quarto - reran file UNSUCCESSFULLY - uninstalled/reinstalled everything - everything works now! Part of the issue prior was that the editor didn't even display the .rmd files properly - the whole file appears like a text file, none of the code lines were color coded, code chunks did not have "run cell/run above" buttons. After the reinstalling, everything appears properly and file renders successfully. Unsure why the first installation didn't run things properly, but alas, it's forever the mythical "turn it off and back on" phenomenon
I apologize for jumping straight in with my problem! I want to say I appreciated your content! very clear and easy to follow!
I can't run a simple "Hello World" It just says source("c:\path_to_rscript"). I thought by default it comes with all tools for R?
Let's say you have the following "hello_world()" function: hello_world <- function(name) { message("Hello world", name) } After running source("c:\path_to_script"), you need to attach the debugger to the function, e.g. debugonce(hello_world) or for multiple calls, specify: debug(hello_world) Then, call the hello_world("test") function. This should engage the debugger.
i see no need for this if you are a RStudio user.
It helps greatly with more advanced features to have the R session run separately from the IDE instead of inside it. You can quickly end up having RStudio run into a few hiccups.
Is it possible to create different types of quarto documents, I mean website, book, etc. in Positron IDE?
You will have to go through the command palette. Open it by pressing CNTRL + SHIFT + P (Windows) or CMD + SHIFT + P (macOS). Then, type: Quarto: Create Project From there, you have the option of default, website, blog, book, or manuscript.
@@thecoatlessprofessor7674 Thank you a lot!
Thank you very much for the explanation. I cannot read .csv from local folder to plot figure or table. I added in _quarto.yml [static-dir: data] but in shinylive it does not found the file.
You shouldn't be able to. The Shiny application is running in a virtual file system instead of your local file system. Thus, the data.csv file you have will not be present. You can add data to a shiny app by following: tutorials.thecoatlessprofessor.com/r-shinylive-data-include/include-download-from-url.html
I would like to see one of your videos on how to upgrade Positron IDE
Okidokie. I’ll record something later today.
At the moment this seems almost identical to using a Jupyter notebook in VS Code, but I guess the ambitions for it are big!
It's similar; but there are some features that are MIA and other features that reorganization different portions. For instance, the jupyter tab is now being reported inside of the variables panel (note issue at: 11:33.), the in-cell notebook debugger is missing, and the python setup process is painless.
Thanks for the video but this is by no means the experience of Copilot/ No way this would replace the natural use of CoPilot in Rstudio or Vsc..
I agree completely! Unfortunately, this is the only way for someone who has access to GitHub Copilot to take advantage of their subscription within the Positron IDE at the moment due to licensing issues, c.f. github.com/posit-dev/positron/issues/476 The Posit team are aware of the limitation and are planning for improvements around the first release candidate.
Thanks🎉
Great; please can you share the link for me to download positron ?
See video description for link to repository. I have two videos on the channel showing the download steps for macOS/Windows
@@thecoatlessprofessor7674thanks, I have figured it out!
Do you think 4 gb rtx3050 enough for data analysis?
The Positron IDE and Python are RAM and CPU hungry. Unless you are fitting a neural network/doing deep learning, the amount of RAM on a GPU is unlikely to play a role in being able to do data analysis effectively.
I like to place the activity bar at the top of the primary side bar as it's neater.
I’ll have to give that a go. Thanks for the suggestion!
Great video!! Is it possible to load GitHub Copilot in Positron?
It’s not possible to use a GitHub copilot extension due to MS licensing issues in Positron. If you have a Copilot subscription, the only way forward is to use {chattr} R package. Otherwise, you will need to stay in VS code or switch to an LLM that has an extension on OpenVSX.
This thing is just a rehash of what we already have with Code, as this software is a fork of it, and marimo and jupyter.
Not at all. The set up here is instantaneous and it's using a new high-performance R kernel and Language Server Protocol implementation called Ark that is licensed under the MIT License, c.f. github.com/posit-dev/ark
Posit-Ron by Posit. 😮😅🎉😊
Heh, nice!
Thanks for an excellent practical introduction to python in Positron!
Glad it was helpful!
This should be good in the future, especially for R. But they need to enable remote ssh / dev containers! On their list, but not yet there.
Yup, it's early days for the new IDE. If you already leaped to VS Code for more advanced features, this IDE is probably missing some features of your current workflow.
Is there support for using this IDE with Databricks?
You can establish a connection using odbc to a Databricks cluster via its connection panel, c.f. solutions.posit.co/connections/db/databases/databricks/
@@thecoatlessprofessor7674 Thank you!
I couldn't find the "zoom" option in the plots? Is is still there in Positron or is is just in Rstudio?
There is no option yet in the Positron IDE for zooming on plots. You can only focus different windows. They are tracking it as a feature in: github.com/posit-dev/positron/issues/2270
Great and thanks for sharing this. Is it possible to edit a chosen theme and change/apply a different background color for example?
Yes, you can select a theme and, then, personalize it by adding into the user settings. Use CMD + SHIFT + P on macOS or CNTRL + SHIFT + P on Windows and search for: Preferences: Open User Settings (JSON) Next, use the following to change the sidebar color only under the Monokai theme: ``` "workbench.colorCustomizations": { "[Monokai]": { "sideBar.background": "#347890" } } ``` Switch [Monokai] with the relevant theme name and use relevant keys via: code.visualstudio.com/api/references/theme-color Section on Customizing a Theme: code.visualstudio.com/docs/getstarted/themes#_customize-a-color-theme

Yes i am loving it so far, seemless experience with R and Python, i never liked working with Python in R studio, that was a mess for me tbh, Positron is a breeze. Quarto works fine too. So far i haven't encountered any issues, except that i am not able to move the panes around.😅😂
Mmm, what happens when you try to drag and drop different parts of the interface? Also, what happens when you click on the layout button in the upper right corner of Positron?

It works great with Quarto! There’s a bit of setup required prior to creating a Quarto document. See: m.czcams.com/video/Xs6UnArkG4c/video.html
@@thecoatlessprofessor7674 Awesome, thank you Professor once again for sharing the resources and keeping us abreast with new developments making data analytics even more exciting.
Thank you so much for creating this video!
Glad it was helpful!
Thanks. This was helpful. One thing I was absolutely missing is that, on Windows, ctrl-enter runs the line and sends the output to the console. Still a lot I don't understand about the functionality, but at least at this point I can _use_ it.
Could you clarify a bit on the functionality remark? Is there a particular use case you are after or are you trying to understand where the editor would fall in your workflow?
@@thecoatlessprofessor7674 Well, one thing I wonder about is running a chunk of code --- and getting the output in the console, or the plot displayed --- like you can do by highlighting a chunk and pressing the run button in RStudio. I guess for people who use this kind of IDE, that's not desirable ? Better to ctrl-enter ? ... And then basically everything with the debugger. I can't make heads or tails of how to use it.
So, I think there's a lot of questions surrounding an analysis using Quarto instead of just an R script? Does that sound about right? In that case, I would say you still have the ability to run code cells by using Cmd/Ctrl+Enter for a single line, Cmd/Ctrl + Shift + Enter or the "Run Cell" button for the entire cell. If you want to create in the R script file a similar "cell" appearance, you need to use `#+` instead of the python version of `# %%`. It's really good to develop keyboard muscle memory instead of using a point-and-click mouse as that takes additional time to complete a task, e.g. pressing a run button. Regarding the debugger, have you check out this video? czcams.com/video/p_4ZS-nnQ2Q/video.html
@@thecoatlessprofessor7674 Thanks. For my comments, no, nothing about Quarto. Just running a script. I still can't figure out how to run a chunk of the script. But more fundamentally, why this isn't a simple press of a button. Like, obviously, that's not how people use this software. Or they set cells or breakpoints or something if they want to do that. I just haven't quite figured the mentality of using this software. (I'm not familiar with VSCode, just RStudio and Spyder). ... I do think a few issues come down to things being in beta. Your debugging video was helpful. But, for example, trying to use Run and Debug; it tells me I don't have an R debugger; and then when I try to install from the options, it tells me it's not compatible with Positron. I take it this is just a beta issue, or I just have no idea what I'm doing. ... It's no biggy. None of this I need to figure out right away. Just trying to see if this kind of software will improve what I do, or if I'm just a RStudio and Spyder person.
Prove me wrong but this is just vscode 😅
The Positron IDE is a _fork_ of the open source Visual Studio Code (OSS - Code). So, it should feel a lot like VS Code in certain areas. One huge benefit to this approach: Access to VS Code extensions published onto OpenVSX.
With much better IDE experience for data workflows! VScode data analysis experience is a mess with chaotic interpreter manager, subpar dataframe viewer via 3rd party plug-ins and a missing variable viewer pane
Actually VS Code can be set in a very similar manner for Python with the Data Wrangler Extension for data frame viewing (it is official Microsoft Extension) and a variable pane is present when running code through an interactive jupyter window (it can be set in the settings when running a line of code to be automatically send to a jupyter window). However, in Positron it is great that all this functionality is available out of the box and also for R because in VS Code I never found a suitable R extension to work with.
I agree it's really nice that a lot of the functionality is just _there_ without needing to setup the editor. Psst, the variable panel is still present in the panel bar when using a Jupyter notebook ;) Though, none of the variables will appear nor will the debugger/breakpoints work correctly in notebook view (so a slight downgrade from the current status quo in VS Code for Python).
Great 🎉
How about a video of the basic functionality of Positron ? Coming from RStudio and Spyder, I'm having some difficulty understanding the basics of how to use Positron. Like, to get output in the console or plots window, do you have to make the call from the console ? Or, am I being stupid or missing the point of the software ?
Yes! That's coming a little later today. I had to do some last minute traveling this weekend that prevented me from showing a workflow video. In the interim, you can use Cmd + Enter to run individual lines inside of the editor. They'll automatically be populated over to the Console. Similarly, any graphing functions like ggplot() or plot() will appear inside of the "Plot" window on the lower right. This fork of VS Code for DS isn't necessarily explained well at the moment. So, I wouldn't worry too heavily. Again, it's early days. Be prepared to ask questions.
Check out: czcams.com/video/-jhTjOK4vQ8/video.html Let me know what you think. This is just exploring the data side. I'll need a separate one for the R packages component...
Not working properly, error no xxxx file found
Can you provide a bit more details on the error? Is the error associated with the Shiny for Python or Shiny for R demo? Did you accidentally save the `app.R`/`app.py` into the home directory, e.g. `~/`, instead of into a subfolder like `~/Documents` or `~/Desktop`?
@@thecoatlessprofessor7674 It was downloaded from positron itself, but in some other videos it explains with GitHub installation, It worked then. Thank you for your prompt reply.
Hei! Do you know if there's some way to have different colour for code and output in the console?
Not that I'm aware of. I do know that if you directly write into the console there is some highlighting that is applied. However, once the code is executed then it is just treated as output. Since they tried to stick a bit close to what is possible with VS Code's theming, maybe check inside the theme file? github.com/posit-dev/positron/blob/f82368fc01eb72ff844d304174eeb81a585477ce/extensions/theme-defaults/themes/light_modern.json The reference spec for a VS Code theme is over at: code.visualstudio.com/api/references/theme-color You could also raise this as a question on the Positron repository's discussion board: github.com/posit-dev/positron/discussions
Thanks for the video. Can you do one for installing Positron IDE in Fedora Linux?
Sorry, I can't! I do not have a VM setup for Fedora Linux.
@@thecoatlessprofessor7674 Ok, no problem.
Is Positron a flavour of VS Code?
Yes, it is a standalone IDE that is built ontop of the open source version of VS Code. github.com/microsoft/vscode
Have you tried Codeium with Positron? It seems to work for me but I need to compare to other IDEs.
Is Positron IDE replacing Rstudio?
No, Positron is not replacing RStudio. Posit will still support the RStudio IDE. Per the FAQ page: Is RStudio going away? No. We are committed to maintaining and updating RStudio. While Positron and RStudio have some features in common, some R-focused features will remain exclusive to RStudio. We began developing Positron as part of our mission to support open-source data science in multiple languages, including R and Python. If you're currently using RStudio and are happy with the experience, you can continue to enjoy RStudio. RStudio includes 10+ years of applied optimizations for R data analysis and package development. github.com/posit-dev/positron/wiki/Frequently-Asked-Questions#is-rstudio-going-away
Very helpful. Thanks for sharing this.
Glad it was helpful!
Thank you so much! Can you please direct me to the next video in your tutorial flow, if I know nothing about R? I understand we need Rstudio as well, but if I have an intel mac I need something else..? (or maybe somebody in the comments can direct me..) Thank you!
I don't think I have any "intro R" lectures public. Outside of installing R and RStudio, you might want to setup a compiled code toolchain; but, that will likely come much later down the road for you!
@@thecoatlessprofessor7674 Thank you!
Thanks
Welcome
Very good.
Thanks!
After entering the command 'macrtools::macos_rtools_install()' I am receiving the following error "Timeout of 60 seconds was reached". This is related to the download of gfortran. Any suggestions?
I think this was an issue that was resolved over on the project's GitHub page: github.com/coatless-mac/macrtools/issues/16 The short rundown: there was either an internet connection hiccup or CRAN's servers briefly were updated during the time the installer tried to download gfortran.
Very nice 👍
Thank you 👍
Not sure if I have misunderstood the process? When I render the doc in R-Studio, everything runs as it does in this video. When I open the html file it produces separately of the rendering process in a web browser it just shows text of the Shiny code and not the app.
The reason everything "works" in RStudio is because the Shinylive application is being run through a local server. If you directly double-click on the shinylive rendered .html, the app will not load in a browser without it being launched with permissions to look at the local file system, c.f. quarto-webr.thecoatlessprofessor.com/qwebr-troubleshooting.html#directly-accessing-rendered-html So, you will need to either publish it using any ol' web server (GitHub Pages, Netlify, Quarto Pub, ...) and share the link or setup the necessary local modifications.
👍
Happy it helped!
I guess we're a weird lot, and there's not to many of us that need to know this. Maybe if you danced while you did it, or made someone keep their finger on a car or some junk. thanks a zillion btw.
No worries; happy it helped!
