See FAQ: http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-do-lattice_002ftrellis-graphics-not-work_003f BTW: don't use jpg for plotting if you can - they routinely look ugly. > B. When the 'bwplot' line alone is submitted, y labels are values 1 to 6, > not actual distinct values of y$maxthreads. That's because maxthreads is not a factor - you can convert it to one. See below. > (C. I would, of course, prefer to produce plots for all distinct values of > x$maxthreads in a single swoop, on a single figure). That's what I was about to suggest. Don't loop over the tasks - use the power of lattice. I think this should be close to what you want: bwplot(factor(maxthreads) ~ time | factor(tasks), x) cu Philipp -- Dr. Philipp Pagel Lehrstuhl für Genomorientierte Bioinformatik Technische Universität München Wissenschaftszentrum Weihenstephan Maximus-von-Imhof-Forum 3 85354 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/ ______________________________________________ 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.
