[R] Re : AUC under spline curve

[ssim at lic.co.nz]

Dear R list,

I  have fitted cubic regression spline with fixed degree of freedom to a
set of data using package mgcv. Now I want to calculate the area under the
spline curve. Someone has suggested me to use trapezoidal rule. Do you know
if someone has written a package that will carry out that analysis, and
where can I download it ?

Thanks in advance.
