Alex, corr.test in psych will give you a matrix of correlations, a matrix of sample sizes, and a matrix of probabilities.
You can combine the correlations and the probabilities to form what you want: try the following: > library(psych) > examp <- corr.test(sat.act) > mat.c.p <- lower.tri(examp$r)*examp$r + t(lower.tri(examp$p)*examp$p) > mat.cp Bill On Oct 26, 2011, at 6:03 AM, AlexC wrote: > Thank you for your quick reply and helpful advice. > > Using this argument allows me to do what I needed to do > > Now the only other thing I wanted to accomplish was to obtain the top half > of the matrix with p values > and the bottom half with the correlations, to observe the significant > correlations.
