Many thanks. Is there a way to give me the number of the row, if I have the row name? B.
a= object 'w' = name > match('w', names(a)) # or > which(names(a)=='w') # or but deletion should work with the number and/or with the name. ______________________________________________ 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.
