clones.giniIndex: Gini index of clones

In bcRep: Advanced Analysis of B Cell Receptor Repertoire Data

Description

This function calculates the Gini index of clones.

Usage

clones.giniIndex(clone.size = NULL, PDF = NULL)

Arguments

clone.size	Vector containing clone sizes
PDF	PDF project name (see Details)

Details

This function calculates the Gini index of clones. Input is a vector containing clone sizes (copy number). The Gini index measures the inequality of clone size distribution. It's between 0 and 1. An index of 0 represents a polyclonal distribution, where all clones have same size. An index of 1 represents a perfect monoclonal distribution.

The PDF character string should be only the project name (without ".pdf"). A figure called "PDF"_Lorenz-curve.pdf will be saved to the working directory. The Lorenz curve represents the clone distribution.
