Cor in r p value interpretation

Although the cor function finds the correlations for a matrix, it does not report probability values. cor.test does, but for only one pair of variables at a time. corr.test uses cor to find the correlations for either complete or pairwise data and reports the sample sizes and probability values as well.Key output includes the p-value, graphs of groups, group comparisons, R 2, and residual plots.
