Jan, libary(lattice) rownames(zz) <- xx colnames(zz) <- yy levelplot(zz)
will not work -- levelplot needs a data frame with zz, xx and yy values next to each other, so read about data.frame(), rep() and as.vector(zz); you will need the each= argument for one of xx or yy. Sounds like you'd be helped by using package sp, see also http://r-spatial.sourceforge.net/ and look for the graph gallery, function spplot. -- Edzer ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
