Dear All,

just discovered in Frank Harrels library (package) Hmisc:
Area under curve defined by arbitrary x and y vectors, using trapezoidal rule and assuming x sorted appropriately

trap.rule <- function(x, y) sum(diff(x) * (y[-1] + y[-length(y)]))/2

Wow :ok:

! The cream of the crop of programming art!

The epistemological value of probability theory is based on the fact
that chance phenomena, considered collectively and on a grand scale,
create non-random regularity. Andrey Kolmogorov
