p-values of correlation matrix
Have a look at function rcor.test() from package ltm, e.g., library(ltm) mat <- matrix(rnorm(1000), 100, 10, dimnames = list(NULL, LETTERS[1:10])) rcor.test(mat) rcor.test(mat, method = "kendall") rcor.test(mat, method = "spearman") I hope it helps. Best, Dimitris
Hello, I have a data frame containing several parameters. I want to investigate pair wise correlations between all of the parameters. For doing so I used the command cor(data.frame, method=???spearman???), the result is a matrix giving me the correlation coefficients of each pair, but not the p-values. Is it possible to get same matrix showing just the p-values instead of the correlation coefficients? As far as I know the command cor.test just works for two given vector, but not for a whole data frame.
