As we dig deeper into Stata or R debate, a few questions have come up.


Question 1: One of the things Stata does well is the way it constructs new variables (see example below). How to do this in R?

We can rewrite it as-is using for loops in R, which is slow and not elegant. What’s the elegant way to write this in R? I haven’t used plyr yet… Time to learn it?
