[R] Extract character from the end of a string
I have a list of names that look like this, with some ending in an * and others not: Steve Young* Joe Montana* Tom Brady Daunte Culpepper ... I want to create a variable that = 1 if the name ends in * and = 0 otherwise. Please help! -- View this message in context: http://r.789695.n4.nabble.com/Extract-character-from-the-end-of-a-string-tp3621732p3621732.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org 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] Extract character from the end of a string
Hi, This answer is predicated on the assumption that you are using list in its English sense. ## character vector with the names x - c(Steve Young*, Joe Montana*, Tom Brady, Daunte Culpepper) ## using grepl() and taking advantage of how logical data is stored to get 0/1 data as.numeric(grepl(\\*$, x)) See ?regexp for more details on regular expressions, ?grepl and ?TRUE for documentation on logical values Hope this helps, Josh On Thu, Jun 23, 2011 at 11:06 PM, jwehr jglandw...@gmail.com wrote: I have a list of names that look like this, with some ending in an * and others not: Steve Young* Joe Montana* Tom Brady Daunte Culpepper ...
