methods

Sample Quantiles

## S4 method for signature 'CompositionMatrix'
quantile(x, ..., probs = seq(0, 1, 0.25), na.rm = FALSE, names = TRUE)

Arguments

• x: A CompositionMatrix object.
• ...: Currently not used.
• probs: A numeric vector of probabilities with values in $[0,1]$.
• na.rm: A logical scalar: should missing values be removed?
• names: A logical scalar: should results be named?

Returns

A numeric matrix.

Examples

## Data from Aitchison 1986
data("hongite")

## Coerce to compositional data
coda <- as_composition(hongite)

## Mean
mean(coda)

## Quantile
quantile(coda)
