colAnyNAs-xgCMatrix-method: Check if any elements in a row (column) of a matrix-like...

In sparseMatrixStats: Summary Statistics for Rows and Columns of Sparse Matrices

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)

## S4 method for signature 'xgCMatrix'
rowAnyNAs(x, rows = NULL, cols = NULL)

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.

Details

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

Value

Returns a logical vector of length N (K).

• 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)
