You probably want something like
subset(dataset, year == 1970)
and loop through the years.
Or, perhaps even classier, would be
datalist <- split(dataset, as.factor(year)) results <- lapply(datalist, myAnalysisFunction)
-roger

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.
Thanks, JGG.
