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.
