After some private email with some high level programmer (Gabor), I have
the solution and I can answer to my own question :-)
The problem was 1° to define a function B( ) available only in a
function A( ) (for code safeness) and 2° to define B( ) elsewhere than
in A( ) (for code readability)

Not that I know of. It will be available to anything using the same
environment as a(), which in the case of
Ok, I saw FUNx
So, I reformulate my question : is there a way, without nesting b( ) in
a( ), to make b( ) available only in a( ) ?

Just to clarify, what Duncan was referring to as the
alternative was nesting the definition of one function
in another, e.g. look at FUNx in by.data.frame --
FUNx is available to by.data.frame but is not
visible outside of by.data.frame .

Well, the main idea was the to limit the existance of a function.
a( ) need b( ) but no other function will need b(). So I would have like
to let b( ) exists localy only when a( ) is called, not elsewhere.

It depends what you mean by 'hiding', you can start the function
names with a dot and then they are not listed by ls(), so this
is kind of hiding.

function() TRUE
Personally i would not do this though.

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
