Sure. You can use nchar() to find out how long the string is. teststring - 01asap05a substr(teststring, 1, nchar(teststring)-1) [1] 01asap05 On Mon, Jun 14, 2010 at 9:47 AM, glaporta glapo...@freeweb.org wrote: Dear R experts, is there a simple way to remove the last char of a text string? substr() function use as parameter start end only... but my strings are of different length... 01asap05a - 01asap05 02ee04b - 02ee04 Thank you all, Gianandrea -- Sarah Goslee http://www.functionaldiversity.org __ 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.
