In MatrixGenerics: S4 Generic Summary Statistic Functions that Operate on Matrix-Like Objects

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, ..., 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, ..., 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,
  ..., drop = TRUE)

colQuantiles(x, rows = NULL, cols = NULL, probs = seq(from = 0, to = 1,
  by = 0.25), na.rm = FALSE, type = 7L, ..., 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, ..., 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,
  ..., 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, NAs are excluded first, otherwise not.
type	An integer specifying the type of estimator. See stats::quantile(). for more details.
...	Additional arguments passed to specific methods.
drop	If TRUE a vector is returned if J == 1.

Details

The S4 methods for x of type matrix, array, 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.

Examples

  mat <- matrix(rnorm(15), nrow = 5, ncol = 3)

  mat[3, 3] <- Inf
  mat[4, 1] <- 0
  
  print(mat)
