In that case we need to tell it that a number can include a dot. Additionally the following simplify the regular expressions by assuming any number of non-numeric followed by numeric fields strapply(MyString, "(\\D+)([.0-9]+)", c)[[1]] strapply(MyString, "(\\D+)([.0-9]+)", ~ list(s1, as.numeric(s2)))[[1]] -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.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.
