pedigreeTools

The pedigreeTools package offers a suit of functions for pedigree analyses, including: sorting and editing pedigree data, computing inbreeding, additive relationships and functions of it (e.g., cholesky derived from a pedigree, inverse of a numerator relationship matrix). The package was originally co-developed by Douglas M. Bates and Ana I. Vazquez and was incorporated in the lme4 R-package. Recently, pedigreeTools evolved to an stand-alone package. We have added new features for pedigree edition, analysis of data from self-pollination and for subsetting pedigrees.

Developers: Ana I. Vazquez & Douglas M. Bates. Paulino Perez-Rodriguez & S. Avadhanam.
