Hello Akkineni,

This bug has already been reported and we have a tentative solution that we are testing.  I'll send you a copy of the modified code once we finish testing.

> Hello all,
> I am using the heatmap.2 function in the gplots package. I

> matrix i pass to the function. I used the statement,

> where z, is the matrix of data. The output i want should have 
> the rows reordered along with the dendrogram and the columns 
> should be in the original order without any dendrogram. For 
> the above statement i am getting an error:
> 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)
> I also tried using ,
> heatmap.2(z,Colv=NULL,dendrogram="row",col=redgreen(75))
> for which i am getting the output, but the columns are 
> reordered. How can this be done for the way in which i want
