Use matplot() and save intermediate things such as in
n <- 100
x <- 2*pi* seq(1:n)/20
mx <- cbind(r1 = 1+5*cos(x) + rnorm(n),
r2 = 1+7*sin(x) + rnorm(n),
r3 = 1+7*sin(x)+5*cos(x)+rnorm(n))
matplot(x, mx, type = 'b')
# or if you really want other colours (and no points, e.g.)
matplot(x, mx, type = 'l', col = c("red", "blue", "black"))
