Don't sorry about n it is only necessary for using a and b which are
the upper and lower limit of integration and n is the # of
sub-intervals. You can ignore all else and use x and y. I will fix
the documentation soon. I did a rather bad job on that help document.
kindest regards,

Thank you, seems to be the right thing for me. But what is this "n" for? The
number of iteration steps as mentioned on other pages for the simpson rule?
"number of divisions" as said on the help page I don't understand. ("a" and
"b" can be ignored, if I got it right?!). Thanks again!

simp() in the StreamMetabolism package may do the trick. I have used
this on time series of chemical constituent masses.

Hi,
I want to know the area under a curve, which is not given as a function, but
as values in a time series. It is not a smooth curve, but switches often
between positive values and zero (the values describe the moisture in the
soil over a year, one entry is one day). I already tried
