Calculates quantiles for each row (column) of a matrix-like object

Description

Calculates quantiles for each row (column) of a matrix-like object.

Usage

rowQuantiles(x, rows = NULL, cols = NULL, probs = seq(from = 0, to = 1,
  by = 0.25), na.rm = FALSE, type = 7L, ..., useNames = TRUE,
  drop = TRUE)

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
rowQuantiles(x, rows = NULL,
  cols = NULL, probs = seq(from = 0, to = 1, by = 0.25), na.rm = FALSE,
  type = 7L, ..., useNames = TRUE, drop = TRUE)

## S4 method for signature 'ANY'
rowQuantiles(x, rows = NULL, cols = NULL,
  probs = seq(from = 0, to = 1, by = 0.25), na.rm = FALSE, type = 7L,
  ..., useNames = TRUE, drop = TRUE)

colQuantiles(x, rows = NULL, cols = NULL, probs = seq(from = 0, to = 1,
  by = 0.25), na.rm = FALSE, type = 7L, ..., useNames = TRUE,
  drop = TRUE)

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
colQuantiles(x, rows = NULL,
  cols = NULL, probs = seq(from = 0, to = 1, by = 0.25), na.rm = FALSE,
  type = 7L, ..., useNames = TRUE, drop = TRUE)

## S4 method for signature 'ANY'
colQuantiles(x, rows = NULL, cols = NULL,
  probs = seq(from = 0, to = 1, by = 0.25), na.rm = FALSE, type = 7L,
  ..., useNames = TRUE, drop = 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.
probs	A numeric vector of J probabilities in [0, 1].
na.rm	If TRUE, missing values (NA or NaN) are omitted from the calculations.
type	An integer specifying the type of estimator. See stats::quantile(). for more details.
...	Additional arguments passed to specific methods.
useNames	If TRUE (default), names attributes of result are set. Else if FALSE, no naming support is done.
drop	If TRUE a vector is returned if J == 1.

Details

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

Value

a numeric NxJ (KxJ) matrix, where N (K) is the number of rows (columns) for which the J values are calculated.
