Hi everyone, I've been trying to find a function that outputs the Pearson and/or Spearman correlation coefficients for several variables with the associated statistics in one single table/matrix. For what I've been able to understand the Stats package is only able to compute these coeficients/statistics only in defined pairs. This becomes time consuming when we want to determine these measures with, say, 10 variables or more. Does anyone knows a solution to this? Kind regards, Nuno

Check ?cor and example(cor) If the first argument to cor is a matrix, it returns the correlation matrix of all the columns.
