Dear R users,
I have spectral data (say, wavelength vs. extinction coefficient) for which IŽd like to calculate an integral (i.e. the area underneath the curve).
Suppose the (artificial) dataset is
lambda E 1 2 2 4 3 5 4 8 5 1 6 5 7 4 8 9 9 8 10 2
How can I calculate an integral for these values using R?
Many thanks for any help! Regards
Christoph
