R correlation matrix with p-values

WebThe correlate function calculates a correlation matrix between all pairs of variables. Much like the cor function, if the user inputs only one set of variables ( x) then it computes all pairwise correlations between the variables in x. If the user specifies both x and y it correlates the variables in x with the variables in y.
