rowIQRs {MatrixGenerics}

R Documentation

Calculates the interquartile range for each row (column) of a matrix-like object

Description

Calculates the interquartile range for each row (column) of a matrix-like object.

Usage

rowIQRs(x, rows = NULL, cols = NULL, na.rm = FALSE, ..., useNames = NA)

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
rowIQRs(x, rows = NULL, cols = NULL, na.rm = FALSE, ..., useNames = NA)

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

colIQRs(x, rows = NULL, cols = NULL, na.rm = FALSE, ..., useNames = NA)

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
colIQRs(x, rows = NULL, cols = NULL, na.rm = FALSE, ..., useNames = NA)

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

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.
na.rm	If TRUE, NAs are excluded first, otherwise not.
...	Additional arguments passed to specific methods.
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::rowIQRs / matrixStats::colIQRs.

Value

Returns a numeric 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)
  
  rowIQRs(mat)
  colIQRs(mat)
