Dear All:
 
Long ago, I have developed a nice program for color depiction of matrices of certain type, i.e., z[i,j], using "image". The values of z are integers 0:6. In the versions preceding the S-PLUS 6, it used to be a very bright good looking picture with seven very distinctive colors. In S-PLUS 6.2 it turned out to be a pretty dull but still color picture. In the S-PLUS 7, I have only gray scales of dark blue but no colors. I haven't found any set-up function for assigning colors to "image". Can anybody please help with solving the problem.
 
Thank you.
