MMOD: an R library for the calculation of population differentiation statistics.

MMOD is a library for the R programming language that allows the calculation of the population differentiation measures D(est), G″(ST) and φ'(ST). R provides a powerful environment in which to conduct and record population genetic analyses but, at present, no R libraries provide functions for the calculation of these statistics from standard population genetic files. In addition to the calculation of differentiation measures, mmod can produce parametric bootstrap and jackknife samples of data sets for further analysis. By integrating with and complimenting the existing libraries adegenet and pegas, mmod extends the power of R as a population genetic platform.
