In compositions: Compositional Data Analysis

Splitting datasets in groups given by factors

Description

Splits data sets of compositions in groups given by factors, and gives the same class as the data to the result.

Usage

## S3 method for class 'acomp'
split(x,f,drop=FALSE,...)
## S3 method for class 'rcomp'
split(x,f,drop=FALSE,...)
## S3 method for class 'aplus'
split(x,f,drop=FALSE,...)
## S3 method for class 'rplus'
split(x,f,drop=FALSE,...)
## S3 method for class 'rmult'
split(x,f,drop=FALSE,...)
## S3 method for class 'ccomp'
split(x,f,drop=FALSE,...)
          

Arguments

x	a dataset or a single vector of some type
f	a factor that defines the grouping or a list of factors
drop	drop=FALSE also gives (empty) datsets for empty categories
...	Further arguments passed to split.default. Currently (and probably) without any use.

Value

a list of objects of the same type as x.
