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.

Thanks,
Renuka
