any Are Some Values True?

Description

Given a set of logical vectors, is at least one of the values true?

Usage

any(..., na.rm = FALSE)

Arguments

...	zero or more logical vectors. Other objects of zero length are ignored, and the rest are coerced to logical ignoring any class.
na.rm	logical. If true NA values are removed before the result is computed.

Details

This is a generic function: methods can be defined for it directly or via the Summary group generic. For this to work properly, the arguments ... should be unnamed, and dispatch is on the first argument.

Coercion of types other than integer (raw, double, complex, character, list) gives a warning as this is often unintentional.

This is a primitive function.

Value

The value is a logical vector of length one.

Let x denote the concatenation of all the logical vectors in ... (after coercion), after removing NAs if requested by na.rm = TRUE.

The value returned is TRUE if at least one of the values in x is TRUE, and FALSE if all of the values in x are FALSE (including if there are no values). Otherwise the value is NA (which can only occur if na.rm = FALSE and ... contains no TRUE values and at least one NA value).

S4 methods

This is part of the S4 Summary group generic. Methods for it must use the signature x, ..., na.rm.
