Thanks, guys... but it seems these suggestions won't work.
Let me try to be more specific with a simple example:
Y<-list()
Y[[1]]<-function(u) sqrt(u)
Y[[2]]<-function(u) sin(u)
Y[[3]]<-function(u) 1/2*u
I wanted something equivalent to
Ybar<-function(u){
1/3*(Y[[1]](u) + Y[[2]](u) + Y[[3]](u))
}
but with arbitrary length(Y) and without using any loops. Also, I can't
allow for discretization, since I must be able to evaluate Ybar at any u, as
I'm going to integrate it with the function "integrate".
Thanks again,
Eduardo Horta
