R Screencasts

Awesome data analysis screencasts from a top Data Scientist

If you’re looking for real-world examples of live data analyses, you’ve come to the right place.

David Robinson, a highly experienced Data Scientist, has recorded many screencasts where he analyses data that he’s never seen before. These are fantastic examples of how to think about approaching an analysis. You couldn’t ask for a better mentor!

The recordings were done as part of a weekly R programming challenge called TidyTuesday. All code is shared and all datasets are publicly available.

What you can learn

This is a wealth of knowledge for new and experienced analysts alike! In each video you’ll learn:

How to approach the analysis
What packages and methods are being used and why
Handy R tips and tricks
How to get unstuck when something doesn’t lead anywhere
