Not exactly true or, at the very least, misleading.

The help for heatmap _should_ be read:

"heatmap() uses layout and draws the image in the lower right corner  
of a 2x2 layout. Consequentially, it can not be used in a multi column/ 
row layout, i.e., when par(mfrow= *) or (mfcol= *) has been called."

You are, of course, free to look at the code for heatmap() and modify  
it to suit your purposes. Or perhaps use image().
