Get a Boolean Environment Variable

Description

A convenience wrapper to Sys.getenv.

Usage

get_boolean_envvar(x, stop_on_failure = FALSE)

Arguments

x	The name of the Environment Variable.
stop_on_failure	Throw an error instead of returning FALSE if the environment variable is not set or cannot be converted to boolean.

Details

As Sys.getenv seems to always return a character vector, the class of the value you set it to does not matter.

Value

The value the environment variable is set to, converted to boolean. FALSE if the environment variable is not set or cannot be converted to boolean. But see Arguments: stop_on_failure.
