Try placing the column names into labCol and the rownames into labRow
e.g.heatmap.2(mat,dendrogram=c("none"),
Rowv=F, Colv=F, labRow = seq(-7.5,7.5,by=5), labCol=seq(-3,3,by=2))

Schalk,
Thats a great function! The only question is, is it as flexible as
heatmap.2?
I figured out how to get it from rearranging the rows and columns but I
can't figure out how to label the rows and columns? What I like about the
heatmap.2 is that it gives a grid and histogram of the heatmap
Hi bioinformatics_guy
I think you are looking for the "image" function:
image(mat)
The heatmap.2 function does hierarchical clustering on rows and columns and
then orders the rows and columns according to the results of the clustering.
Image simply plots the matrix.

I have a file of the following form
-11 -10 -9 -8
-10 -9 -8 NA
-9 -7NA NA
-8NA NA NA
So basically a NxN matrix of log scores. I want to get a heatmap of these
log scores but I'm having a problem.
I'm using the following code
library(gplots)
data=read.table("filein.txt",header=
4 matches
