sexbias.test {hierfstat}

Test for sex biased dispersal

Description

Test whether one sex disperses more than the other using the method described in Goudet etal. (2002)

Usage

sexbias.test(dat,sex,nperm=NULL,test="mAIc",alternative="two.sided")

Arguments

dat

a data frame with n.locs+1 columns and n.inds rows

sex

a vector containing the individual's sex

nperm

the number of permutation to carry out

test

one of "mAIc" (default), "vAIc","FIS" or "FST"

alternative

one of "two.sided" (default),"less" or "greater"

Value

call the function call
