Hi:
here is something that works on your token.list object:
> paste(lapply(token.list,paste,collapse=", "),collapse="\n") [1] "a, b, c\nd, e"
You can't use data.frames, as your vectors dont have the same number of elements.
But you still have all the information, in a list. So you can use lapply to compute on elements of this list.
If we decompose, the lapply does:
> lapply(token.list,paste,collapse=", ") $"1" [1] "a, b, c"
$"2" [1] "d, e"
On which we call a paste.
HTH,
Eric

How can I get a multi line string from a vector of string tokens in an easy manner (e.g. for the use as xlab of a plot)?
I have e.g.: > tokens <- letters[1:5] [1] "a" "b" "c" "d" "e"
I search: [1] "a, b, c\nd, e"
I tried:
> nlines <- 2
> ntokens.line <- ceiling(length(tokens) / nlines)
> token.list <- split(tokens, rep( 1:ntokens.line, each=ntokens.line, len=length(tokens)))
$"1"
[1] "a" "b" "c"
$"2"
[1] "d" "e"
I could work with a data.frame, e.g.:
> paste(collapse='\n', apply(token.df, MARGIN=1, FUN=paste, collapse=', '))
but I got an error when converting token.list to a data frame:
> token.df <- data.frame( token.list )
Error in data.frame("1" = c("a", "b", "c"), "2" = c("d", "e"), check.names = FALSE) :
arguments imply differing number of rows: 3, 2
What can I do (other than using a loop now)?
Thanks - Wolfram
