Not sure what the problem is, but although the first call does not work, the second one does: image(Matrix(volcano), col.regions = topo.colors(100), colorkey = TRUE) image(as(Matrix(volcano), "sparseMatrix"), col.regions = topo.colors(100), colorkey = TRUE) -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.
