Test the Truth of R Expressions and Warn

Usage

warnifnot(..., exprs, exprObject, local = TRUE)

Arguments

..., exprs

any number of R expressions, which should each evaluate to (a logical vector of all) TRUE.

exprObject

alternative to exprs or ...: an ‘expression-like’ object, typically an expression, but also a call, a name, or atomic constant such as TRUE.

local

(only when exprs is used:) indicates the environment in which the expressions should be evaluated; by default the one from where stopifnot() has been called.
