Vectorized test for truth robust to NA

Description

These functions work exactly the same as x == TRUE and x == FALSE but by default return FALSE for cases that are NA.

Usage

isTRUENA(x, ifNA = FALSE)

isFALSENA(x, ifNA = FALSE)

Arguments

x	Logical, or a condition that evaluates to logical, or a vector of logical values or conditions to evaluate.
ifNA	Logical, value to return if the result of evaluating x is NA. Note that this can be anything (i.e., TRUE, FALSE, a number, etc.).

Value

Logical or value specified in ifNA.

Functions

x == TRUE
isTRUENA(x)
