Hi there, I have a data frame with a column named "Flags", whose contents are strings containing any of the following characters, multiple characters allowed: A,B,C,D,E,F,G.
Here is the head: GeocodeID PlaceID CountyCode CBSACode StateProvCode PropertyTypeGroupID Flags 1 0 0 0 0 AK 1 ABC 2 0 0 0 0 AK 2 AC 3 0 0 0 0 AK 3 BC 4 0 0 0 0 AK 4 CD 5 0 0 0 0 AK 14 CD 6 0 0 0 0 AK 15 ACDE 7 0 0 0 0 AL 1 I want to select only the rows whose "Flag" element contains the character G. Is there a simple way to do this, or should I perhaps come up with a different system of flags, which is totally up to me? Thanks, Alex [[alternative HTML version deleted]] ______________________________________________ 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.
