[R] several functions in the same plot

[Liaw, Andy]

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.

HTH,
Andy

Subject: [R] several functions in the same plot


Hello,
Is it possible to plot several functions on a same plot? 
example: 3 functions : f(x), g(x), h(x) 
I would like to obtain one graphic with x-axis and y-axis 
and the 3 functions plotted to compare them.
Vincent
