Function global_env 

pub fn global_env() -> Environment

👎Deprecated since 0.10.0:

Use Environment::global() instead

The “global” environment

use extendr_api::prelude::*;
test! {
    Environment::global().set_local(sym!(x), "hello");
    assert_eq!(Environment::global().local(sym!(x)), Ok(r!("hello")));
}
