check_namespace function

Checks if namespace is available

Use this function if your resource/indicator function requires the namespace of a certain package to be available. An informative error/warning message is printed if that is not the case.

check_namespace(pkg, error = TRUE)

Arguments

• pkg: A character vector of length one indicating a package name for which the namespace is tested
• error: A logical indicating whether or not to promote missing namespace to error. If FALSE, a warning is emitted.

Returns

TRUE, invisible, if the namespace is available. An error message if error = TRUE, FALSE and a warning otherwise.
