Get the name of an environment

environment_name(envir)

Arguments

envir: An environment.

Value

A non-empty character string.

Details

This function returns what environmentName(envir) with a few exceptions. One exception is that it, instead of "base", returns "package:base" for baseenv(), which is the same environment as pos.to.env(grep("package:base", search())). This distinguishes from "base" returned for getNamespace("base"), which is not the same environment. Another exception is when environmentName() returns an empty string, e.g. when envir <- new.env(). In such cases, it returns the hexadecimal string that is outputted by print(envir).
