Chris, You can use the as.is or stringsAsFactors argument in read.csv to prevent that strings are converted into factors. See ?read.csv for the details.

I've been searching the R-help archives for posts by you and Hadley as a way to learn ggplot details so I appreciate your help to the R community. I wasn't aware of the levels option in the factors function. In my real application I get the data using read.csv and factor assignment happens automagically. Is there a way to control the level assignments at the input stage? Can't see anything to that effect in help. Sorry for the cut & paste error ... getting used to Xemacs on Windows. I used emacs years ago on Unix but now my environment is Windows. So far I find the Xemacs/Ess combo to be very powerful and flexible. Just need to get used to C-x C-c etc differences.
