In const-ae/sparseMatrixStats: Summary Statistics for Rows and Columns of Sparse Matrices

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

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

## S4 method for signature 'xgCMatrix'
rowAnyNAs(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.
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).

See Also

• matrixStats::rowAnyNAs() and matrixStats::colAnyNAs() which are used when the input is a matrix or numeric vector.

• For checks if any element is equal to a value, see rowAnys().

• base::is.na() and base::any().

Examples

  mat <- matrix(0, nrow=10, ncol=5)
  mat[sample(seq_len(5 *10), 5)] <- NA
  sp_mat <- as(mat, "dgCMatrix")
  colAnyNAs(sp_mat)
