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

In HenrikBengtsson/matrixStats: Functions that Apply to Rows and Columns of Matrices (and to Vectors)

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, ..., useNames = TRUE)

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

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

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

Arguments

x	A vector, a list, a matrix, a data.frame, or NULL.
idxs	A vector indicating subset of elements to operate over. If NULL, no subsetting is done.
...	Not used.
rows	A vector indicating subset of rows to operate over. If NULL, no subsetting is done.
cols	A vector indicating subset of columns to operate over. If NULL, no subsetting is done.
useNames	If TRUE (default), names attributes of the result are set, otherwise not.

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)))
