[BioC] Error in Heatmap: Could not find function "heatmap.2"

[Benjamin Otto]

Hi Samantha,

try the command sessionInfo() and check wether the "gplots" package is loaded. If not, then load it our self. This package should contain the heatmap.2.

cheers

Benjamin

Should I have installed additional packages to plot the heatmap, or is this a general bug?  FYI, my version of R is R 2.10.1
