WebMay 27, 2024 · If you are willing to install the Hmisc R package (available in CRAN) it supports a rcorr() function which: is robust, accepts a numeric matrix (or 2 numeric matrics !) as input, removes NAs according to the pairwise comparisons, and returns both r and p value measures for the pairwise comparisons. Webrcorr Computes a matrix of Pearson's r or Spearman's rho rank correlation coefficients for all possible pairs of columns of a matrix. Missing values are deleted in pairs rather than deleting all rows of x having any missing variables. Ranks are computed using efficient algorithms (see reference 2), using midranks for ties.
