hierfstat (version 0.04-14)

samp.within: Shuffles a sequence within groups defined by the input vector

Description

Used to generate a permutation of a sequence 1:length(lev). observations are permutted within blocks, according to the vector lev passed to the function.

Usage

samp.within(lev)

Arguments

lev
a vector containing the group to which belongs the observations to be permuted.

Value

  • a vector 1:length(lev) (with blocks defined by lev) randomly permuted. Usually, one passes the result to reorder observations in a data set in order to carry out permutation-based tests.
