<scp>hierfstat</scp>, a package for <scp>r</scp> to compute and test hierarchical <i> F</i>‐statistics

Abstract The package hierfstat for the statistical software r , created by the R Development Core Team, allows the estimate of hierarchical F ‐statistics from a hierarchy with any numbers of levels. In addition, it allows testing the statistical significance of population differentiation for these different levels, using a generalized likelihood‐ratio test. The package hierfstat is available at http://www.unil.ch/popgen/softwares/hierfstat.htm .
