Hi Hinda,
I don't know how advanced the tools for simulating genetic data are in
R. Maybe we are not very far, or not that far yet. The package rmetasim
is said to perform individual-based population genetics simulation, so
it may be worth having a look there:
http://cran.r-project.org/web/packages/rmetasim/index.html
Otherwise, there is a package GeneticsPed in the Rgenetics project for
handling pedigree data:
http://bioconductor.org/packages/devel/bioc/html/GeneticsPed.html
but it seems to be in an early stage of development, and it does not
seem to perform data simulations.
Good luck,
Thibaut.
