I assume there was a notice o your console that there were warnings, right? You should offer the full texts of warnings and error messages. Here the full text of the first and second warnings: > warnings()[1:2] $`log scales cannot be changed via 'update'` update.trellis(all_plots, xlab = c("Predictor 1", "Predictor 2", "Predictor 3"), scales = c(list(log = TRUE, equispaced.log = FALSE), list(log = TRUE, equispaced.log = FALSE), list(y = list(log = T, equispaced.log = FALSE)))) $`'x' is NULL so the result will be NULL` rep(scales[[nm]], length.out = 2) The first one is telling you why the results should be different than you expect. I'm not entirely sure what the second one is telling you, but it doesn't sound good. -- David Winsemius Alameda, CA, USA ______________________________________________ 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.
