abundances: Vector of frequencies of frequencies

In ville-kinnula/SPEC: Supervised Classification under Partition Exchangeability

Description

A function to calculate frequencies of frequencies or the combined frequencies of frequencies of two vectors.

Usage

abundances(freqs, freqs0 = NULL)

Arguments

freqs	A frequency table of data vector x.
freqs0	A second optional frequency table to be merged to the freqs parameter.

Details

Freqs0 is optional. It is used in the case of calculating abundances of test data when the frequencies of the training data are already known. Freqs0 is table(x0) ,where x0 is training data. Abundances of any kind of data vector x can be calculated with table(table(x)).

Value

This function returns a named vector that is used to calculate probabilities and make classifications.

Examples

set.seed(111)
x<-rpois(10,10)
abundances(table(x))

y<-rpois(2,10)
abundances(table(x), table(y))
