is_void: is_void

In daviddoret/GRCRToolkit: GRC Toolkit

Description

Systematically testing for variable "emptiness" in R is a bit of a pain. This is a shortcut function that tests if a variable x is NULL or NA. If x is a vector, is_void does not test the elements of the vector, but returns FALSE because a vector is an object that is neither NULL nor NA.

Usage

is_void(x, ...)

Arguments

x	a variable

Value

boolean

Examples

is_void(NULL)
is_void(NA)
is_void(0)
is_void(c(NA,NA,NA))
