I am using the rcorr function within the Hmisc package in R to develop Pearson correlation coefficients and corresponding p-values when analyzing the correlation of several fishery landings time series. The data isn't really important here but what I would like to know is: how are the p-values calculated for this? It states that the asymptotic P-values are approximated by using the t or F distributions but I am wondering if someone could help me find some more information on this or an equation that describes how exactly these values are calculated.
