R help - Mar 2006 - A question on plot

I’m trying to obtain a plot of given function, say the density of a
normal, in which I could indicate the area under the curve between two
points (a,b).
I.e. the P(a<X<b). Could anyone indicate me which is the instruction for
obtain such a shadow area under a curve?
I guess the solution is not difficult, but I can not find the procedure.

Thanks

Try

RSiteSearch("shade area under curve")
