R Question

How can I create a correlation matrix in R?

I have 92 set of data of same type.

I want to make a correlation matrix for any two combination possible.

i.e. I want a matrix of 92 x92.

such that element (ci,cj) should be correlation between ci and cj.

How do I do that?


An example,

 d <- data.frame(x1=rnorm(10),
cor(d) # get correlations (returns matrix)
