lmPerm
Permutation Tests for Linear Models
This is the original package developed by Bob Wheeler that I took over after his sad demise.
I just maintain the package and keep it up-to-date with CRAN standards and rules.
The package is available on the CRAN web site: https://cran.r-project.org/package=lmPerm
In case you wish using a version not yet on the CRAN web site you can use the devtools
package:
install.packages("devtools") ## if not already installed
devtools::install_github("mtorchiano/lmPerm")
