>From the help for cor (from the stats package):
"If x and y are matrices then the covariances (or correlations) between the
columns of x and the columns of y are computed."
So if you make a matrix with each column corresponding to one of your
variables, you can get what you're after.
For future reference, help.search("correlation") turns up the proper page as
the first suggestion.
Hope this helps,

Subject: [R] Creating a correlation Matrix
Hi all:
I have a question on how to go about creating a correlation matrix. I have
a huge amount of data....21 variables for 3471 times. I want to see how
each of the variables correlate to each other. Any help would be
appreciated, including which package and which functions I should use to do
this.
Thanks,
