Hi all, This message is in response to: http://www.mail-archive.com/r-help@stat.math.ethz.ch/msg93690.html Basically, in SAS you can retrieve the partial correlation coefficients using: proc reg data = ch11q02; model y = x1 x2/pcorr1 pcorr2; run; quit; Is there a comparable way to retrieve these values in R? Thanks, Harold
