I fit a GAM to turtle growth data following methods in Limpus &
Chaloupka
1997 (http://www.int-res.com/articles/meps/149/m149p023.pdf).
I want to obtain figures similar to Fig 3 c & f in Limpus & Chaloupka
(1997), which according to the figure legend are "expected size-at-age
functions" obtained by numerically integrating "size-specific growth
rate
functions derived using cubic B-spline fit to GAM predicted values".
I was able to fit the cubic-B spline, but I do not know how to
"numerically
integrate" it.
You need to give us the function and the appropriate limits of
integration.
Can anybody help please?
