Thanks to zero_one for offlist pointer to reshape2::melt: library(reshape2) data.frame <- melt(array.3d, varnames=c("lon", "lat", "lev"), value.name="conc") library(lattice) levelplot(conc ~ lon * lat | factor(lev), data = data.frame) works! thanks all, Tom Roche <tom_ro...@pobox.com> ______________________________________________ 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.
