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 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 = TRUE)

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

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

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

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

## S4 method for signature 'ANY'
colAnyNAs(x, rows = NULL, cols = NULL, ...,
  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.
...	Additional arguments passed to specific methods.
useNames	If TRUE (default), names attributes of result are set. Else if FALSE, no naming support is done.

Details

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

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)

rowAnyNAs(mat)
colAnyNAs(mat)
