display a matrix, including the values, as a heatmap

Question

What I\'d like to do is take this matrix:

> partb
                0.5  1.5   1a   1b   -2   -3
A1FCLYRBAB430F 0.26 0.00 0.74 0.00 0.00 0.00
A1SO604B523Q6         


        

Answer 1

Try heatmap.2 from the gplots package. The cellnote and notecol parameters control the text placed in cells. You'll probably want dendrogram = "none" as well.
