[R] Reg : Hello all.. help needed regarding heatmaps

[R. Michael Weylandt]

If you don't mind using an external (but very popular) graphics
package known as ggplot2 it's super easy:

https://learnr.wordpress.com/2010/01/26/ggplot2-quick-heatmap-plotting/

I'm sure it can be done in base graphics as well, but I'll leave that
to someone else.

It's also well implemented in gplots::heatmap.2 (that is, the
heatmap.2 function from the gplots package which, name
notwithstanding, is unrelated to ggplot2). Run

if(!require(gplots)) {install.packages("gplot"); library(gplot)}
example(heatmap.2)

for some examples.
