## S4 method for signature 'CompositionMatrix'
mean(x, ..., ignore_na = FALSE, ignore_zero = TRUE)

Arguments

• x: A CompositionMatrix object.
• ...: Currently not used.
• ignore_na: A logical scalar: should missing values be stripped before the computation proceeds?
• ignore_zero: A logical scalar: should zeros be stripped before the computation proceeds?

Returns

A numeric vector.

Details

Examples

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

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

## Mean
