Hi,
Just to show there are always different ways to handle such problems:
You could also prepare a matrix (or data.frame) containing those data (in fact, I suspect you do have data in that form).
> names1 <- letters[1:10]
> names2 <- letters[1:20]
> data <- cbind(genre=rep(c("female","male"),c(10,20)), names=c(names1,names2))
> data
genre names
[1,] "female" "a"
[2,] "female" "b"
#[...] continued
> split(data[,"names"],data[,"genre"]) $female [1] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j"
$male
[1] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j" "k" "l" "m" "n" "o" "p" "q" "r" "s" "t"
See ?split

Hi Robin,
regarding you first question you could use,
str <- c("one","two","three") paste(str, collapse=", ")
hoewver, describing what you actually want to do I'd use,
names1 <- letters[1:10] names2 <- letters[1:20] lis <- lapply(1:2, function(x) get(paste("names", x, sep=""))) names(lis) <- c("female", "male") lis
I hope this helps.
Best, Dimitris
