RV: RV coefficient

In guiblanchet/countComm: Counting procedure to be more cost effective when sampling ecological communities

Description

Calculates an RV coefficient.

Usage

RV(X, Y)

Arguments

X	A matrix with the same number of rows as Y
Y	A matrix with the same number of rows as X

Details

RV calculates the RV coefficient between two matrices.The RV coefficient is a multivariate generalization of the squared Pearson's correlation. In package FactoMineR, the function coeffRV calculates other variations of the RV coefficient and propose a test for it. This function was designed to calculate only the basic RV coefficient making it much faster than coeffRV.

Value

The RV coefficient. A numeric value ranging between 0 and 1
