bhattacharyyaCoefficient {LymphoSeq} | R Documentation

## Bhattacharyya coefficient

### Description

Calculates the Bhattacharyya coefficient of two samples.

### Usage

    bhattacharyyaCoefficient(sample1, sample2)

### Arguments

`sample1` | A data frame consisting of frequencies of antigen receptor sequences. "frequencyCount" is a required column.
`sample2` | A data frame consisting of frequencies of antigen receptor sequences. "frequencyCount" is a required column.

### Value

Returns the Bhattacharyya coefficient, a measure of the amount of overlap between two samples. The value ranges from 0 to 1 where 1 indicates the sequence frequencies are identical in the two samples and 0 indicates no shared frequencies.

### Examples

    file.path <- system.file("extdata", "TCRB_sequencing", package = "LymphoSeq")

    file.list <- readImmunoSeq(path = file.path)

    productive.aa <- productiveSeq(file.list, aggregate = "aminoAcid")

    bhattacharyyaCoefficient(productive.aa[["TRB_Unsorted_32"]],
       productive.aa[["TRB_Unsorted_83"]])
