I think the previous answer (to use lm() ) is not necessarily the best option.

Since what you want is the definite integral (area under the curve), you can just use one of the existing definite integration tools (sorry, I don't recall the names because I don't use them).

If you want to get a "smoothed" curve to remove errors in your data points, I'd recommend fitting a spline and integrating under that.
