Hi,
I'd appreciate help with this. I have a data matrix with one column, called
f in the example below, a factor. I'd like to subtract the means from each
of
other columns for each level of the factor. That is, in the example, to go
from the first matrix below to the second. I know SWEEP will take out means,
but I want to do this for each level of the factor.
f x
1 2
1 0
2 0
2 4
2 2
f xnew
1 1
1 -1
2 -2
2 2
2 0
Thanks
