It's trivial -- and many R functions do this. ?outer,?sapply for example.

Once can also return a function. ?approxfun for example

Trivial example that shows how to use ... to pass in extra arguments to fun

chooseFun<-function(dat=1:10,fun=mean,...)fun(dat,...)
chooseFun()
x<-rnorm(100)
chooseFun(x,median)
chooseFun(x,hist)
chooseFun(x,hist,col='gray')
