Hello all, I am using the heatmap.2 function in the gplots package. I want to supress the reordering of the columns of the data matrix i pass to the function. I used the statement, heatmap.2(z,Colv=FALSE,dendrogram="row",col=redgreen(75)) 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
