This is what you are trying to get at I think: dev.off() ## start with a new graphics device # X11() or postscript() #par(mar = c(3,3,1,3), oma = c(0,0,0,0), mgp = c(2, 1, 0), bg = "white") par(mar = rep(5,4)) plot(x<-rnorm(100),y<-rnorm(100), ylab = "This is y", xlab = "This is x") z<-rnorm(100)*250 par(new=T) ## Tell R not to reinitialize graphic device ## for subsequent plots plot(x,z,col='blue',axes=F, xlab="", ylab="") axis(side=4,col.axis='blue', labels = T) mtext("This is z", 4, 2, col = "blue") par(new=F)
