rowAnys {MatrixGenerics}R Documentation

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

Description

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

Usage

rowAnys(x, rows = NULL, cols = NULL, value = TRUE, na.rm = FALSE, ...)

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
rowAnys(x, rows = NULL,
  cols = NULL, value = TRUE, na.rm = FALSE, dim. = dim(x), ...)

## S4 method for signature 'ANY'
rowAnys(x, rows = NULL, cols = NULL, value = TRUE, na.rm = FALSE, ...)

colAnys(x, rows = NULL, cols = NULL, value = TRUE, na.rm = FALSE, ...)

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
colAnys(x, rows = NULL,
  cols = NULL, value = TRUE, na.rm = FALSE, dim. = dim(x), ...)

## S4 method for signature 'ANY'
colAnys(x, rows = NULL, cols = NULL, value = TRUE, na.rm = FALSE, ...)

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.

value

The value to search for.

na.rm

If TRUE, NAs are excluded first, otherwise not.

...

Additional arguments passed to specific methods.

dim.

An integer vector of length two specifying the dimension of x, essential when x is a numeric vector. Note, that this is not a generic argument and not all methods need provide it.

Details

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

Value

Returns a logical vector of length N (K).
