[R] Evaluation of variable assigned to a function name

[Uwe Ligges]

Wel, just let the user give the function in form of an argument, say 
"foo", and use your code so that


bar <- function(x, ....., foo){
    if(missing(foo)) foo <- Namespace::my.func
    .....
}


but perhaps I misunderstood your question.
