Hello R list. I am sure this is an easy question, please forgive my ignorance of R. I have a panel data set (25 years) and I would like to break it up by year, and run a few tests. How is this done in R? In STATA it is quite simple (keep if year =1970). If someone could give me an example of how to do it for a single year I am sure I could make a little loop to do it for all 25.
