Dear All,
I have two matrices A (40 x 732) and B (40 x 1230) and would like to calculate
correlation between them. I can use: cor(A,B, method=pearson) to calculate
correlation between all possible pairs. But the issue is that there is one-many
specific mappings between A and B and I just need
Well, it would be possible to set something up to select out just the
right pairs each time, but on my system the following
a - matrix(rnorm(40 * 732), 40)
b - matrix(rnorm(40 * 1230), 40)
system.time(cor(a,b,method = pearson))
takes about a tenth of a second so any more elective approach will
Thanks a lot, Michael.
