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.

Value

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

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.

See Also

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

Examples

# NOT RUN {
 x <- rnorm(n = 1000)
 x[seq(300, length(x), by = 100)] <- NA
 stopifnot(anyMissing(x) == any(is.na(x)))

# }
