The ‘clinfun’ package in R can perform a Jonckheere-Terpstra test, with the exact test as the default if the sample size is less than 100 and there are no ties, otherwise the test defaults to the permutation test.

This test or a test with a similar function is sometimes called “ordinal chi-square” test. In Agresti, the method used is called the linear-by-linear association model. In R, the test can be performed by permutation test with the coin package. Association in ordinal tables can also be tested with Kendall’s tau correlation.This 'Rcpp'-based package implements highly efficient functions for the calculation of the Jonckheere-Terpstra statistic.
