[R] shade between two curves

Is there a function that can shade the region between two arbitrary curves? For example, how can I fill in the area between these two plotted curves? x - 1:10 y - x + rnorm(10) z - x + 10 + rnorm(10) plot(x, y, type = l, ylim = c(0,20)) lines(x, z) I would appreciate any help. David

polygon() will do it. That's a frequently-discussed topic on this list, so there are plenty of examples in the archives, and also some on the R Graph Gallery. Sarah On Fri, Feb 4, 2011 at 8:03 AM, David Bickel davidbickel.com+rh...@gmail.com wrote: Is there a function that can shade the region
