[R] String manipulation

[Gabor Grothendieck]

Or perhaps this minor simplification:

vars <- c("names1", "names2")  # or use paste or ls(pattern="names[1-2]")
lis <- lapply(vars, get)
names(lis) <- c("female", "male")

: 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.
