Dear list members,
Does anyone know how to calculate in R integral of bivariate distribution of
discrete points suche as the following
x       y
1       1
2       2
3       9
5       11
7       7
12      20
13      10
But I've thousands of x,y points with x always increasing: I'm talking about
spectral signature.
I think I need some function that "constructs" (not interpolates) a polyline
from these x,y points and then calculate the underlying area, because I've
to compare several distributions.

Could anyone help me?

Thanks
