Eduardo - I'd guess that Ybar = function(u)mean(sapply(Y,function(fun)fun(u)))
will do what you want, but without a reproducible example, it's hard to tell. - Phil Spector Statistical Computing Facility Department of Statistics UC Berkeley spec...@stat.berkeley.edu On Tue, 16 Nov 2010, Eduardo de Oliveira Horta wrote:
Hello there I have a list, Y, and each component of that list is a real-valued function (that is, Y[[i]](u) returns a number). I was wishing to build the mean function and the first thing I thought of was Ybar<-function(u){ mean(Y[[1:n]](u)) } but obviously this doesn't work, since Y[[1:n]] is not allowed at all. Any elegant suggestions? I really would like to avoid something like Ybar<-function(u){ for (i in 1:n){ Ybar<-Ybar + Ybar[[i]](u) } Ybar<-1/n*Ybar } Thanks in advance!
