[R] Hiding a function

Hi the list

Is it possible to 'hide' a function from the user ? I cut a big fonction in sub
function and I would like to hide the sub function, just like if I declare them
in the big function :



a <- function(x){
  b <- function(y){y^2}
  d <- function(y){y^3}
  b(x)+d(x)+2
}
a(2)
# [1] 14
b(2)
# Error :

I would like the same, but with external declaration (for readability) :


b <- function(y){y^2}
d <- function(y){y^3}
a <- function(x){

  b(x)+d(x)+2
}
a(2)
# [1] 14
b(2)
# Error

Is it possible ?

Thanks

Christophe
