r-cran-permute - 0.9-7-1 main

Implements a set of restricted permutation designs for freely exchangeable,
line transects (time series), and spatial grid designs plus permutation of
blocks (groups of samples). ‘permute’ also allows split-plot designs, in which
the whole-plots or split-plots or both can be freely-exchangeble or one of the
restricted designs. The permute package is modelled after the permutation
schemes of Canoco 3.1 by Cajo ter Braak.
