Yes, but why do you want one? (You don't need summary, just coef, in the second line, and you also do not need an intercept.) For a single regressor as here, just cor(ctl, trt). > ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14) > trt <- c(4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69) > summary( lm(ctl ~ trt) ) > summary( lm(scale(ctl) ~ scale(trt)) ) -- Brian D.
