Quantile {DescTools}

(Weighted) Sample Quantiles

Description

Compute weighted quantiles (Eurostat definition).

Usage

Quantile(x, weights = NULL, probs = seq(0, 1, 0.25), 
         na.rm = FALSE, names = TRUE, type = 7, digits = 7)

Arguments

x

a numeric vector.

weights

an optional numeric vector giving the sample weights.

probs

numeric vector of probabilities with values in [0,1].

na.rm

a logical indicating whether missing values in x should be omitted.

names

logical; if true, the result has a names attribute. Set to FALSE for speedup with many probs.

type

an integer between 1 and 9 selecting one of the nine quantile algorithms detailed below to be used. Currently only types 5 and 7 (default) are implemented.

digits

used only when names is true: the precision to use when formatting the percentages. In R versions up to 4.0.x, this had been set to max(2, getOption("digits")), internally.

Details

The implementation strictly follows the Eurostat definition.

Value

A named numeric vector containing the weighted quantiles of values in x at probabilities probs is returned.
