Inferring patterns of migration from gene frequencies with R
(or S-Plus), Version 1.2.0
Jarle Tufto
Abstract:
A collection of R (and S-Plus) functions and some
additional c-code for estimating the pattern of migration
in a subdivided population from genetic differences
generated by local genetic drift is described. The method
is applicable to migration matrices of any form.
Submodels defining the general form of the migration
matrix can be written by the user. Functions are also
provided for carrying out likelihood ratio tests between
alternative models such as the island model and the
stepping stone model, or between alternative user defined
submodels. In addition, plots of predicted and observed
covariances can be made to assess the fit of a selected
model. Finally, code for computing the asymptotic
eigenvalue variance effective size of a subdivided
population is provided.
