Dear Peter,
the call works for me; e.g.
x <- matrix(rnorm(100), ncol = 4)
heatmap.2(x, dendrogram="none", Colv = FALSE, Rowv = FALSE)
There seems to be something wrong with your matrix z ...
Best,
Matthias

Thanks Matthias,
I tried that, but received the following error message:
Error in image.default(1:nc, 1:nr, x, xlim = 0.5 + c(0, nc), ylim =
0.5 + :
dimensions of z are not length(x)(+1) times length(y)(+1)

heatmap.2(z, dendrogram = "none", Rowv = FALSE, Colv = FALSE)
should do what you want.

Using the heatmap.2 function, I am trying to generate a heatmap of a
2 column x 500 row matrix of numeric values. I would like the 1st
column of the matrix sorted from the highest to the lowest values -
so that the colors reflected in the first column of the heatmap (top
to bottom) go from red to green.
After sorting the matrix (z), I tried the following command, but the
data remains clustered.
heatmap.2((z),col=greenred(100),dendrogram=NULL,Rowv=FALSE)
I also tried the following, but the data remained clustered.
heatmap.2((z),col=greenred(100),Colv=1:ncol(z))
ANY IDEAS??
Thanks so much,
Peter
