I doubt what you have in mind makes too much sense, but changing the
environment of a function foo to and environment env can be done using
environment(foo) <- env

Hello,
Is there a syntax to set the environment of a function when this function is
defined?
The best I could come up with so far is using a wrapper function:
foo_internals<- function(x) {"Code of the function"}
foo<- function(x) {
environment(foo_internals)<-as.environment(target_environment)
foo_internals(x)
}
But I would like to know if there is a cleaner syntax.
There are two reasons why I would like to have a function defined with an
environment different then the local one:
The first is to develop a function that will go in a package: there might be
more things loaded in my R_GlobalEnv than what will be available to the
function when its environment will be the namespace of the package, so I
would like to restrict right away the environment of the function that I
develop in my local enviroment to what will be their environment in 'real
life'.
The other reason would be to have a function written in a package act as if
it was from another package by giving it the environment of this other
package.
Thanks for your suggestions and comments,
Frederic
