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.

It looks like you have missing observations. With the use argument, you

The problem is not with R, but with the specification of the
