This is precisely the problem. ## Show the error [message] y <- rnorm(100) y[c(3,6,9,12,20,56)] <- NA g <- rep(1:2, rep(50,2)) sm.density.compare(y, g, model="equal") ## One way around the problem is row-wise deletion of NAs na.omit(cbind.data.frame(y,g)) with(na.omit(cbind.data.frame(y,g)), sm.density.compare(y, g, model="equal")) Regards, Mark.
