What is GenomeAdmixR?

A package to perfrom individual-based simulations of genome evolution with ancestry.

Demonstration GenomeAdmixR

Thijs Janzen gave a presentation demonstrating GenomeAdmixR (then named isoSIM) at the R User Group at the University of Groningen, Groningen, The Netherlands. You can watch his presentation here (audio starts after 1 min)
