If the functions are all evaluated at the same set of x values, then you can use something like: matplot(x, cbind(fx, gx, hx), type="l") where fx, gx and hx are the function values. The advantage of this over plot() followed by lines() is that the limits on y-axis automatically account for all three functions.
