checkEnvironment: Check if an argument is an environment

Description

Check if an argument is an environment

Usage

checkEnvironment(x, contains = character(0L))
assertEnvironment(x, contains = character(0L), .var.name)
testEnvironment(x, contains = character(0L))

Arguments

x

[ANY] Object to check.

.var.name

[character(1)] Name for x. Defaults to a heuristic to determine the name using deparse and substitute.

contains

[character] Vector of object names expected in the environment. Defaults to character(0).

Value

• Depending on the function prefix: If the check is successful, all functions return TRUE. If the check is not successful, assertEnvironment throws an error message, testEnvironment returns FALSE and checkEnvironment returns a string with the error message.
