colQuantileC

Fast colunm- and row-wise quantile of a matrix.

Description

Fast calculation of column- and row-wise quantiles of a matrix at a single probability. Implemented via compiled code, it is much faster than the equivalent apply(data, 2, quantile, prob = p).

Usage

colQuantileC(data, p)
rowQuantileC(data, p)

Arguments

data

a numerical matrix column-wise quantiles are desired. Missing values are removed.
p

a single probability at which the quantile is to be calculated.

Details

At present, only one quantile type is implemented, namely the default type 7 used by R.

Value

A vector of length equal the number of columns (for colQuantileC) or rows (for rowQuantileC) in data containing the column- or row-wise quantiles.
