Hi, all, I have a column like the following: ID TIME sub_001 0 sub_001 24 sub_002 0 sub_002 24 sub_003 0 sub_003 24 sub_004 0 sub_005 24 .. ..
is there a way for me to just extract the numeric numbers from the ID column, omitting sub_? thanks, -- View this message in context: http://r.789695.n4.nabble.com/extract-number-from-a-mixture-of-character-and-number-tp4636659.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.
