Hi, I am able to get the correlations as: xxx<-cbind(x1,x2,x3) yyy<-cbind(y1,y2,y3)
cor(xxx,yyy) This yields same results as yours. But I could not get the p values yet. thanks abou >>> Ista Zahn <[email protected]> 4/3/2012 8:05 PM >>> Hi, For the correlations you just need to understand how matrix indecies work in R: cor(cbind(x1, x2, x3, y1, y2, y3))[4:6, 1:3] I'll leave it to you to figure out the p values part.
