David Robinson (aka drob) is one of the best known R programmers.

Since a couple of years David has been sharing his knowledge through streaming screencasts of him programming. It’s basically part of R’s #tidytuesday movement.

Alex Cookson decided to do us all a favor and annotate all these screencasts into a nice overview.

Here you can search for video material of David using a specific function or method. There are already over a thousand linked fragments!

Very useful if you want to learn how to visualize data using ggplot2 or plotly, how to work with factors in forcats, or how to tidy data using tidyr and dplyr.

For instance, you could search for specific R functions and packages you want to learn about:

Thanks David for sharing your knowledge, and thanks Alex for maintaining this overview!

Anyone other #rstats people find @drob's #TidyTuesday screencasts useful?

I made a spreadsheet with timestamps for hundreds of specific tasks he does: https://t.co/HvJbLk1chd

Useful if, like me, you keep going back and ask, "Where in the video did he do [this thing] again?"
