Sorry, I just realized I didn't send this to the list! (See below)

Thanks for all the help! All is working fine now.

If anyone knows of a more straightforward way to change the "Value" string
for the Key, please let me know (just to satisfy my curiosity).  I got it to
work by modifying the source code (specifically, "heatmap.2.R " in the
gplots package).

However, before, I didn't make the call
source("heatmap.2.R")

before I called
source("mysillyheatmap.R")

Making the additional call to " heatmap.2.R" fixed everything.

Thanks again for all your help!
