Another simple question. I would like to plot three graphs one the same plot with different colours. Say red, blue and black. Here are the functions. r1<-1+5*cos(2*pi*seq(1:100)/20)+rnorm(100) r2<-1+7*sin(2*pi*seq(1:100)/20)+rnorm(100) r3<-1+7*sin(2*pi*seq(1:100)/20)+5*cos(2*pi*seq(1:100)/20)+rnorm(100)
plot(r1, type = "n") points(r1, col = "red", pch = 19) ## see also ?lines points(r2, col = "blue", pch = 19) points(r3, col = "black", pch = 19)
