[R] number of observations used in cor when use="pairwise.obs"

Dear R gurus, to compute the correlation matrix of "n" variables with "n_obs" observations each, possibly including NA, I use cor(M, use="pairwise.obs") where m is a "n" x "nobs" matrix. Now I want to know the number of observations actually used in this computation, namely for each pair of colum

[R] expand.grid applied to a matrix

Dear R gurus, I'm looking for a way to expand a matrix to a data frame as detailed below: given a Matrix M with attribute dimnames=list(c("a","b"),c("u","v")), return a data frame df.M with df.M$row df.M$col df.M$val "a""u" M["a","u"] "b""v" M["b". "v
