compositions (version 1.10-1)

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

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.
