anyMissing {matrixStats}R Documentation

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.

Starting with R v3.1.0, there is anyNA() in the base, which provides the same functionality as anyMissing().

Examples

 x <- rnorm(n = 1000)
 x[seq(300, length(x), by = 100)] <- NA
 stopifnot(anyMissing(x) == any(is.na(x)))
