Yes; search terms ' "ranked set sampling" "r-project" ' ... does  
produce a very complete book-length piece: "Robust Nonparametric  
Statistical Methods" (2010) by Hettmansperger and McKean which has a  
section on the question posed at printed pg 53 (pg 64 of the pdf  
version) and on second print page cites R code available:

(And I note that Terpstra and McKean are co-authors and that the same  
institution.)
