Using return() within a for loop makes no sense: only the first one will be returned.
Steve, Mea culpa. Didn't catch that.
How about: alldf.B = subset(alldf, stream=='B') # etc...
I used to do each stream manually, like the above, and want to learn how to loop through all of them ...
Also, have a look at unique(alldf$stream) or levels(alldf$stream) if you want to use a for loop on each unique value.
... which unique() and levels() will probably do. Will test these tomorrow after rading the man pages.
