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 = TRUE)

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

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

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

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

## S4 method for signature 'ANY'
colIQRs(x, rows = NULL, cols = NULL, 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.
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.

Details

The S4 methods for x of type matrix, array, table, 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)
