Is there a way to get a TRUE/FALSE condition as result, when using grep ? c="The file will be updated"
if grep("updated",c)==1 then I get TRUE but How can I deal with grep("new",c) ? it gives integer(0) Thanks in advance. ______________________________________________ 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.
