obtaining p values & CI for a non-parametric correlation matrix
Hello,
I tried to obtain a nonparametric correlation matrix with the following syntax:
by(mydat, mydat$GROUP, function(subset) { matrix <- cbind(subset$WK1FREQ,
subset$WK2FREQ, subset$WK3FREQ, subset$WK4FREQ, subset$BESTDAY) cor(matrix,

Any suggestions are much appreci...
