Isolate a Function from its Environment
Description
Put a function in a "lean" environment that does not carry unnecessary baggage with it (e.g. references to datasets).
Usage
crate(.fn, ..., .parent = topenv(parent.frame()), .compile = TRUE)
Arguments
.fn |
(function() )
function to crate
|
... |
(any)
The objects, which should be visible inside .fn .
|
.parent |
(environment )
Parent environment to look up names. Default to topenv() .
|
.compile |
(logical(1) )
Whether to jit-compile the function.
In case the function is already compiled.
If the input function .fn is compiled, this has no effect, and the output function will always be compiled.
