[R] Pearson and Spearman correlation coeffcients matrix

[Jonathan Baron]

I think "associated statistics" means p-levels.

This post
http://finzi.psych.upenn.edu/R/Rhelp01/archive/5380.html
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
 
 ?cor
 
 and
 
 example(cor)
 
 If the first argument to cor is a matrix, it returns the correlation
 matrix of all the columns.
