Lattice has no facilities for automatic wrapping. However, 1. see ?strwrap to get your strings broken, and ?paste to join them with "\n"-s. 2. You will need to manually find a suitable 'width' for the strwrap call, depending on your device size and layout 3. You will also need to use lines= in par.strip.text, but you should be able to figure out the appropriate value from the results of strwrap. -Deepayan ______________________________________________ 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.
