Description

Test for association between paired samples (with one variable being nri-values), using one of Pearson's product moment correlation coefficient, Kendall's tau or Spearman's rho.

Usage

"cor.test"(x, y, ...)

Arguments

x

Object of class Nri or numerical vector

y

Object of class Nri or numerical vector
