Check if any elements in a row (column) of a matrix-like object is missing

Description

Check if any elements in a row (column) of a matrix-like object is missing.

Usage

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

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
rowAnyNAs(x, rows = NULL, cols = NULL, ..., useNames = NA)

## S4 method for signature 'ANY'
rowAnyNAs(x, rows = NULL, cols = NULL, ..., useNames = NA)

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

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
colAnyNAs(x, rows = NULL, cols = NULL, ..., useNames = NA)

## S4 method for signature 'ANY'
colAnyNAs(x, rows = NULL, cols = NULL, ..., useNames = NA)

Arguments

x

An NxK matrix-like object.

rows, cols

A vector indicating the subset of rows (and/or columns) to operate over. If NULL, no subsetting is done.

...

Additional arguments passed to specific methods.

useNames

If NA, the default behavior of the function about naming support is remained. If FALSE, no naming support is done. Else if TRUE, names attributes of result are set.

Details

The S4 methods for x of type matrix, array, or numeric call matrixStats::rowAnyNAs / matrixStats::colAnyNAs.

Value

Returns a logical vector of length N (K).
