My apologies, I know that this is not a new problem, but I'm not sure how
to find the answer
I want to recursively loop over an object and trim trailing white space.
When I use this function on a list of data.frame I get output like this:
[1] "c(\" many spaces \", \" many spaces \")" "c(\" many spaces
\", \" many spaces \")"
What should I do to recombine the results?
If anyone has a good way to search for this type of question, that would be
appreciated. I tried rseek.org with "recursive", but after wading though
all the rpart references I didn't find something that seemed to help with
this problem.
Thank you very much.
trim <- function(x) {
if(length(x)>1) sapply(x[1], trim)
gsub("^[[:space:]]+|[[:space:]]+$", "", x)
}
tempobj = ' many spaces '
tempvec = c(tempobj, tempobj)
templist = list(tempvec, tempvec)
tempdf = data.frame(x = tempvec, y = tempvec)
trim(tempobj)
trim(tempvec)
trim(templist)
trim(tempdf)
Thank you,
Gene Leynes
