colAnys,xgCMatrix-method {sparseMatrixStats}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

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

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

Arguments

x

An NxK matrix-like object.

rows

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

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.

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::rowAnys / matrixStats::colAnys.

Value

Returns a logical vector of length N (K).
