Dear List, I'm trying to generate a simple heatmap that has each row and column separated by a black line. However, for some reason this only happens for the first and last color. The middle color in my colorpanel() command has an addition horizontal and vertical line that I would like to get rid off. Any suggestions? #my code below my.matrix <- cbind(func.1 = c(1,2,2,1,1,3,1,2,3,1,1,2,2,3,1), func.2 c(2,2,1,1,3,3,1,1,2,2,1,3,3,2,1)) mycol <- colorpanel(n=3,"green","grey","red") heatmap.2(my.matrix,Rowv=FALSE, Colv="Rowv", col=mycol, trace="both", tracecol="black", key=FALSE, symm=FALSE, vline=NULL, hline=NULL) Kind regards, Peter

Sorry, I should have added library(gplots) in the beginning of my code On Sun, Jan 13, 2013 at 5:04 PM, Uwe Ligges <ligges at statistik.tu-dortmund.de> wrote:>> >> mycol <- colorpanel(n=3,"green","grey","red")- - - Peter K Davidsen | MSc, PhD stud. | Centre for Systems Biology | Univ. of Liverpool | Crown Street | L69 7ZB, UK | cell: +44 (0)7428 950501

And now the rest of the code is missing. Please always cite the original message. I deleted it already after my answer. Maybe you should provide it for the others who are familar with that package and can try to help you.
