[R] Matplot & Polygon

[Kitty Lee]

I used matplot to plot multiple lines (over 300 lines). I'd like to draw a polygon and shade the area between upper and lower boundary.

I know the plot function works pretty well with polygon(). How about matplot? I have too many lines and my upper/lower boundaries are formed by many different lines. Matplot seems to be more efficient in plotting our all the lines...or perhaps I'm wrong on this. I'd like to hear other suggestions.

Thanks.
