Thank you all for taking the time to point out that a data frame is not the
same as a matrix! I'll give it another shot when I get home tonight.

a perspective plot but not having any luck after reading the R manual and
several examples found on the Internet.
I have a 100 x 100 matrix of Z data as a tab-delimited text file exported
from Minitab. I read this in t
