anyMissing

Checks if there are any missing values in an object or not

Description

Checks if there are any missing values in an object or not. Please use base::anyNA() instead of anyMissing(), colAnyNAs() instead of colAnyMissings(), and rowAnyNAs() instead of rowAnyMissings().

Usage

anyMissing(x, idxs = NULL, ...)

colAnyMissings(x, rows = NULL, cols = NULL, ...)

rowAnyMissings(x, rows = NULL, cols = NULL, ...)

colAnyNAs(x, rows = NULL, cols = NULL, ...)

rowAnyNAs(x, rows = NULL, cols = NULL, ...)

Arguments

`x`	A `vector`, a `list`, a `matrix`, a `data.frame`, or `NULL`.
`idxs, rows, cols`	A `vector` indicating subset of elements (or rows and/or columns) to operate over. If `NULL`, no subsetting is done.
`...`	Not used.

Details

The implementation of this method is optimized for both speed and memory. The method will return TRUE as soon as a missing value is detected.

Value

Returns TRUE if a missing value was detected, otherwise FALSE.
