Hello, this forum was very helpful yesterday with a simple question I had on
working with tables. What function will I need to use to do the following.
Move matrix a:
A B C D
x 1 2 3 4
y 5 6 7 8
to the mean of B&C and C&D:
x 2.5 3.5
y 6.5 7.5
and then to the mean of B&CB, C&BC, C&CD, and D&CD:
AAB BAB CCD DCD
x 1.75 2.25 3.25 3.75
y 6.25 6.75 7.25 7.75
Thanks again for any help. I'm putting in some good time after work trying
to learn this language and any help would be great.
