[R] Splitting strings
I'm having a Thursday morning mental block, any suggestions on the following would be most appreciated... I have (as an example) surgery = c(d48, d67, dnc37, a75, d10, a78, d31, d55, d1) before each number part the possibilities are c(a, d, dnc), I'm trying to split each element in surgery so that I have, status time d48 d67 dnc 37 a75 d10 a78 d31 d55 d1 I've tried various strsplit approaches but nothing has done what I need. thanks in advance Gary [[alternative HTML version deleted]] __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Splitting strings
one way is the following: data.frame(status = gsub([0-9], , surgery), time = gsub([a-z], , surgery)) I hope it helps.

Re: [R] Splitting strings
This applies the indicated perl-style regular expression where the first backreference (\\D+) is the non-digits and the second backreference (\\d+) is the digits. The two backreferences, but not the entire matched pattern itself, are passed as arguments x and y to the function whose body is the right hand side of the formula in the third argument. That is then simplified using rbind to give the result. library(gsubfn) strapply(surgery, (\\D+)(\\d+), ~ list(lets = x, nums = as.numeric(y)), backref = -2, perl = TRUE, simplify = rbind) More on gsubfn at http://gsubfn.googlecode.com On 8/23/07, Gary Collins [EMAIL PROTECTED] wrote: I'm having a Thursday morning mental block, any suggestions on the following would be most appreciated...
