R Documentation

Is the input an environment?

Description

Checks to see if the input is an environment.

Usage

assert_is_environment(x, severity = getOption("assertive.severity", "stop"))

is_environment(x, .xname = get_name_in_parent(x))

Arguments

`x`	Input to check.
`severity`	How severe should the consequences of the assertion be? Either `"stop"`, `"warning"`, `"message"`, or `"none"`.
`.xname`	Not intended to be used directly.

Value

is_environment wraps is.environment, providing more information on failure. assert_is_environment returns nothing but throws an error if is_environment returns FALSE.

Examples

assert_is_environment(new.env())
assert_is_environment(globalenv())
assert_is_environment(baseenv())
