Details

Several R functions for manipulating objects in environments (such as get and ls) allow specifying environments via corresponding positions in the search path. pos.to.env is a convenience function for programmers which converts these positions to corresponding environments; users will typically have no need for it. It is primitive.

-1 is interpreted as the environment the function is called from.

This is a primitive function.
