[R] integration

[dlavecchia at tiscali.it]

Dear All,
I need to perform a numerical integration of one dimensional 
fucntions. The extrems of integration are both finite and the functions 
I'm working on are quite complicated. I have already tried both area() 
and integrate(), but they do not perform well: area() is very slow and 
integrate() does not converge. Are in R other functions for numerical 
integration of one dimentional functions?

Thanks in advance 

Davide
