Permutation based p-value for the Pearson correlation coefficient {Rfast}

Permutation based p-value for the Pearson correlation coefficient

Description

Permutation based p-value for the Pearson correlation coefficient.

Usage

permcor(x, y, R = 999) 

Arguments

x

A numerical vector with the first variable.

y

A numerical vector with the second variable.

R

The number of permutations to be conducted; set to 999 by default.

Details

This is a very low computational calculation of the p-value. Try it yourselves.

Value

A vector consisting of two values, the Pearson correlation and the permutation based p-value.
