Are Some Values True?

Description

Given a set of logical vectors, are any of the values true?

Usage

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

Arguments

... one or more logical vectors. Other objects are coerced in a similar way as as.logical.default.
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.

Value

Given a sequence of logical arguments, a logical value indicating whether or not any of the elements of x are TRUE.
The value returned is TRUE if any the values in x are TRUE, and FALSE if all the values in x are FALSE.
If na.rm = FALSE and x consists of a mix of FALSE and NA values, the value is NA.

Note

Prior to R 2.1.0, only NULL and logical, integer, numeric and complex vectors were accepted.
