Hi all,

I want to create a simple plot with 2 type='s' lines on it:

plot(a, b, type='s')
lines(x, y, type='s') 

I wish to then fill the area between the curves with a colour to
accentuate the differences eg col=gray(0.95). I cant seem to come up
with a simple method for this. Any pointers in the right direction much
appreciated.

Cheers

Scott
