(maybe better).


I can create a list of subsetted data.frames like this:

Lst = list(subset1 = (subset (blablabla)), subset2 =  
(subset(blabla)))

but I have to provide the component names (subset1, subset2) manually.


lstnames <- paste("subset", 1:2, sep="_")
names(Lst) <- lstnames



I would like to pull the component names from an existing character  
vector, but so far my attempts have failed.


Any advice is appreciated, even if the advice is "don't do that."

Thank you,
