Hi! All, I have 2 correlation matrices of 4000x4000 both with same row names and column names say cor1 and cor2. I have extracted some information from 1st matrix cor1 which is something like this:
rowname colname cor1_value a b 0.8 b a 0.8 c f 0.62 d k 0.59 - - -- - - -- Now I wish to extract values from matrix cor2 for the same rowname and colname as above so that it looks similar to something like this with values in cor2_value: rowname colname cor1_value cor2_value a b 0.8 --- b a 0.8 --- c f 0.62 --- d k 0.59 --- - - -- --- - - -- --- I am running out of ideas. So I decided to post this on mailing list. Please Help!
