hi,

the code below produces me two curved lines.

Now I want to fill the space between these curves with a color and I  
don't have any idea how to do that with R.


I tried it with the polygon() function but it didn't worked out.



Can someone her give me a hint on that?

thanks!





x1 <- c(0.0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0,1.1,1.2,1.3,1.4,
