[R] Shade area under curve?

[Robert Lundqvist]

Hi all,

I've got this graphics question which really should be easy. I want to shade
an area between bounds under a curve. A suitable beginning seems to be the
following:

> plot(dnorm,-4,4)
> segments(-4,0,4,0)
> segments(-2,0,-2,dnorm(-2))
> segments(2,0,2,dnorm(2))

It is the area between -2 and 2 which I want to shade (or something
similar). Hints anyone?

Robert
