thanks

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


Hi, Carol. What is the output of capabilities()?   Does tiff say "TRUE"?  If not, then your system does not support making tiffs.
