Hi,
I want to save the image produced by heatmap.2 in a tiff file. To do so, I call
 tiff(filename ='test.tiff', res = 300)
heatmap.2(c2, col = greenred(200),labCol = "", labRow = "",breaks = seq(-3,3,0.03), trace = "none", dendrogram = "none", keysize = 2, scale = "none")

But I get the following error message after the call of heatmap.2

Error in plot.new() : unimplemented cairo-based device
Error in par(op) : invalid value specified for graphical parameter "pin"

I use R version 2.9.1, system x86_64, linux-gnu

Look forward to your reply,

Carol
