Video

Hey thank you for the video. I saw that you also already have the docker instructions in the package website. I'm hoping to run a simple app with plumber in production in the next few weeks. I was going to just use caddy as a load balancer for multiple plumber instances but I think using Valve should provide better functionality out of the box. Thanks again!

That was one of the best video tutorials I've seen lately, super informative and easy to follow! I cannot wait to test this out with some different datasets. Thanks for the amazing work!

Hi, i'm trying to implementing the algorithm in java and following the same steps i got the same results, so i guess i'm reimplementing it correctly. The only problem is, if i try to use any lat/long coordinates for example, my home adddress lat/long, got a geohash that is totally far away from the addres used. In fact if i use some online tool the hash generated is totally different and correct.

super clear ,easy and concise walkthrough. Amazing

I'm curious how this works. Is it loading the whole file into memory before doing the aggregation? Or the query planner smart enough that it knows it only needs to load 1 line at a time (and then handles keeps track of the required aggregations accordingly)

It isn't fair.

There a chance to show us how to do species distribution modelling using Biomod2 or SDM package

Great video, Josiah! For benchmarking, just a fun FYI in case you didn't know, you can do `summary(benchmark_obj, relative = TRUE)` and it will compare the two in relative terms, which is neat!

Wish i knew more R 😅. Looks useful for helping out the R community with rust 🙂

Nice library 🎉.

Clear explanation.

What it boils down to is that R is at its core a fully featured programming language. To some degree it will always be inherently unsafe, as will any other programming language, simply because by nature they have to be in order to function. Much like a good quality knife is also able to cut you as well as your dinner. There are some shenanigans at play here, but it still pales in comparison to the likes of Java's Fracturiser hidden in minecraft mods or malicious executables.

This whole thing seems suspicious to me. A contract threat research company sets out to find a way to exploit R, and then, (Wa-La!) finds it! Then advertises it like crazy! And in the write-up they specifically reference the usage of R in the Pharmaceutical industry, and even links to a talk by R/Pharma. This whole thing feels like a set up. Was HiddenLayer contracted to do this? By who? Very suspicious that a *potential* exploit got as much coverage as way more damaging *actual* exploits.

I emailed Hadley and he said, you don't have to update R to 4.4.0. Someone in reddit said, it is no use to update R if you use RDS/RDA files from unknown source. Also, for a follow up question, is it possible to combine C, FORTRAN, C++ and Rust code together in one package? I tried to combine C++ and Rust but failed to debugged my R package but I know there's a certain package that uses C and C++ together (EBImage as an example).

What is R used for? Like with syntax like that I understand why it is used [That might be the most beautiful code I've ever seen] But for what like what is its practical applications?

I don't get how it is a huge vulnerability. When you download code from the internet it can run code. cmd() or similar is a common resource in nearly every programming language. There is nearly no scripted programming language where a downloaded module couldn't do that. I guess it might better let them obfuscate because it is calling it indirectly? In general you should assume all downloaded code can run anything within userland within the same user on the machine. Launching a calculator is just something code can do. Any module in any programming language could probably delete all your files or send them off to some server.

1:26 I can confirm that note LOL

I'll be sure to never share this with my legal/sec department. They'd freak out at your blatant use of the R-word (whispers 'risk'). On the other hand, I've been able to take away their dread by filling out copious forms in the past so should they be exposed to your scary talk I know what to do. After all, everyone knows killer-bureaucracy is what truly keeps our corporate networks safe

Thanks for the content. As an R user i don't usually think about this but very informative context!

Very interesting!

Very interesting!

I do write plenty of for loops in R, but they're typically in places where either the speed really doesn't matter (e.g. `for (i in vars) ggplot(...)`) or where there's no way to vectorise the body (e.g. in stochastic simulations where there's a load of stuff going on and the loop depends on what happened in the previous loop, and I'm not that good at using `reduce()`). Typically I do what's easiest to read, and usually when something can be vectorised, it's easier to read that way anyway. If I need it to be fast, I have Julia, which says for loops are good actually since all the code is JITted, although Julia makes vectorising code trivial with its dot syntax (e.g. `log.(x)`).

This is so cool!

Thanks for the intuitive tutorial. But I would like to point out that str::len() method counts bytes instead of characters. Non-alphanumerical characters will return inappropriate results, i.e. nchar2("你好世界") (Hello World in Chinese) returns 12 instead of 4. Interestingly, NA values are 2 bytes. One should use str::chars().count() to count at a higher computation cost than str::len().

I'm currently in an R youtube rabbit hole and this one has been an absolute joy. I tip my fedora to your excellent content, good sir

sudo dnf install helix

A very cool video! I find loops easier to understand and use than the apply functions. However I always had a bad feeling about using them as they are supposed to be inefficient. This video made me feel better about my terrible loopy loops :).

Really great explanation! Saw both part 1 and 2 and now I understand geohashing clearly. Thank you.

which theme is that?

How does one document functions exported from rextendr::document() so the document is readable and can be a reference used in Rstudio? Seeing the arguments are referred to as C objects?

2:02, 16:19, etc What are you typing here to autocomplete typing? Is it some VS code Rust extension?

I was wondering if there is a linear algebra library in extendr (Rust), like RcppArmadillo

Nice brief code, but on my machine I'm getting an error with the pretty: implementation Display statement.

Nice video, and this man has an accent similar to Will of SpaceRex. I like the presentation. The only thing i caught at the end was again a young man in the field of computer science, the third one (and one is from the UK so its not just North American English), who doesn't use the past participle form with have. He said "I've ran" instead of "I've run." It seems to be a phenomenon among younger folks, and I wonder if this grammatical form is just not taught in schools anymore, or is it how people, like his parents or friends are speaking in this region of the world. But, i have noticed Elliott Minns of another CZcams channel (@Dreams Of Code) also using the past tense form of the verb with an auxiliary and not the past participle form of the verb. But, it's the message and content that matters. Good job.

Very well explained.Thank you

R dev here trying to broaden my horizons and wow I'm blown away with the performance! Keep making these!

Thank you for this nice video! What plugin do you use in VS Code to have the option of running/debugging just above the main function?

Super clear and interesting to follow, Thank you!

what happens if your function returns Vec<T>, where T is, say, struct Person { name: String , age: i32 }?

noob here. could you make your own unclass method for matrices to return the values the way you did it my assigning $dims to NULL?

subbed, keep up dwag

Solid video Josiah. Would be interested to see your take on the R6 OOP system next!

Thank you. Great video. I think I can use dots much better now.

amazing content

Hi Josiah - do we know why interleaving is being done?

Keep up the good work Josiah. This is fantastic. Hope to see you hit the 100K subscriber soon.

Is there any cookbook for `extendr` and `rextendr`? Also, how to set up `extendr` or `extendrsrc` in R markdown? When I run a chunk in extendr, it works and saved in environment however, when I knit the rmd file, it failed

2:17 You forgot Plus codes!
