Hi list,
My data set is comprised of 47 columns and about 700 rows.
Most of the values would be around 2, while some will go beyond
in either direction, higher or lower. Is there a way to specify the
parameter of col or others if necessary to have the range of representing
colors be 0----8, and make dark for 2, red for higher than 2 and green
for lower than 2. Is there a way to do this? Thanks a lot for your
suggestions.

All the best,
      Allen
