I think "associated statistics" means p-levels.
tells how to do it and gives and example.
But I think that nobody wants to make a function for this because
it would encourage bad behavior, i.e., snooping through a
correlation matrix looking for "significant" correlations and
then making up a story about how the 5% of them that were
significant at p<.05 were really planned tests.

I believe that the cor function already does what you want. Check
If the first argument to cor is a matrix, it returns the correlation
matrix of all the columns.
