  • Here I illustrate, or introduce if you aren't familiar with it, the package that's called readr, which is part of the tidy verse, and this is the package that we would use to import external files into our R environment as usable R objects. In the tidy verse those would be called Tibbles, but a Tibble is just an enhanced user-friendly version of the data frame. The data frame is the most important rectangular object in R. In a previous video, as part of the introduction R, we've already looked at this function here called read.table and I would just ask you to focus on the fact that it has a dot in it. That's the tell-tale sign that it is part of the base package. read.table is part of the utils package, which is loaded automatically when we start R.

    Hey David, I am a INST perma bull but I found this recent post on Glassdoor from one of their employees, I was wondering if you have noticed or have thoughts on this:
    "There have been significant red flags - especially with the leadership team. The CEO, Dan Goldsmith, recently hired his sister into a C-Suite position. To avoid a conflict of interest, they are making her report to Intructure's Head of Legal - even though it's against Instructure's policy to have family reporting to you. This is wrong for a public company. This upset a lot of people. The flagship product, Canvas, is a cash-cow. Our corporate product, Bridge, is not good. We try to sell it so hard and it's a waste of money. There are more overpaid people in certain departments who crawled their way up the ladder just because they worked at Instructure in the beginning."

      Hi Ryan, Thanks for the pointer. I had NOT noticed that comment (I see it now). My thought is that I (almost) never treat a single data point as valid; I wait for a pattern. The reviews on Bridge, so far, have been good and/or excellent. I can't let a single GD review alter my view. I do think the next quarter is important. I said that last quarter, but we're waiting for quantitative breakouts on bridge. If we don't see those soon, we can get worried I think. Thanks,
