question on graphs and finding area under a curve

Question on graphs: The default case for drawing a graph in R, is where a little space is left on the x and y axis before the first tick i.e. even if I say xlim=c(0,1) -- there will be some space between the edge of the x-axis and where 0 is placed. If I want 0 on the edge, how do I do it in R? Area under the curve: I have a 45 degree line and a curve above or below it. Is there a way in R to find the area between the two?
Hi, integrate.xy in sfsmisc package might help you. Romain
Thanks, Renuka
