I think the answer to your question is: I'm not sure that there's a way to do that in "all of the usual R commands", but you can split up your data first, then run "all of the usual R commands" on them :-) Functions you want to look at are probably: ?split ?by and ?tapply You might try to look at the plyr library first, though: http://cran.r-project.org/web/packages/plyr/index.html It provides some groovy ways to iterate/manipulate sets/subsets of data.
