You could remove the white space also by: library(stringr) levels(bdf$func_feed_grp) #[1] "Filterer" " Gatherer " " Grazer " " Omnivore " #[5] " Parasite " " Predator " " Shredder "
levels(bdf$func_feed_grp)<- str_trim(levels(bdf$func_feed_grp)) levels(bdf$func_feed_grp) #[1] "Filterer" "Gatherer" "Grazer" "Omnivore" "Parasite" "Predator" "Shredder" A.K. ----- Original Message ----- From: Rich Shepard <rshep...@appl-ecosys.com> To: R help <r-help@r-project.org> Cc: Sent: Friday, August 16, 2013 12:01 PM Subject: Re: [R] Plotting Multiple Factors By Dates With Lattice On Fri, 16 Aug 2013, Richard M.

I thought of removing white space (didn't notice the spurious newline) in emacs but did not see that it made a difference. Now I know it does I'll clean up all the files. > I switched the key to "lines" to match the graph.

Again, thanks.
