Hey, I am still working on my heat map (for those who are read my previous post about row.names) Now, I would like to save my heat map.2 in .png or .tiff in order being able to work on the picture in photoshop, but it doesn't work. I'am using (as I have found on some forum) > png("heatmap.2.png) # and it just doesn't work. when I try doing it with:: >jpeg("heatmap.2.jpeg) # it works once every 10 times, but it's a 22kb file. >completely use less !!!
I really need to have high quality image, as I will have to work on photoshop and also I will have to cut and zoom in just some lines of my heatmap. #here is the code I use for my heatmap.2 : >heatmap.2(a_matrix, Rowv=NA, Colv =NA, col=greenred(60), scale="column", >margins=c(7,10), trace="none", density.info=c("none")) Does someone know what I have to do in order to get my heatmap.2.png ??? Do I need some other package (I only use gplots, to allow the heatpmap.2) THANKS for your help Fred [[alternative HTML version deleted]]
