In Bioconductor/MatrixGenerics: S4 Generic Summary Statistic Functions that Operate on Matrix-Like Objects

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, ...,
  useNames = TRUE)

## 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), ...,
  useNames = TRUE)

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

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

## 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), ...,
  useNames = TRUE)

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

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, missing values (NA or NaN) are omitted from the calculations.
...	Additional arguments passed to specific methods.
useNames	If TRUE (default), names attributes of result are set. Else if FALSE, no naming support is done.
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, table, or numeric call matrixStats::rowAnys / matrixStats::colAnys.

Value

Returns a logical vector of length N (K).

Examples

mat <- matrix(rnorm(15), nrow = 5, ncol = 3)
mat[2, 1] <- NA
mat[3, 3] <- Inf
mat[4, 1] <- 0

print(mat)

rowAnys(mat)
colAnys(mat)
