sample.ped

Two pedigrees of different size for testing pedigree operations

datasets

Routines to handle family data with a pedigree object. The initial purpose
was to create correlation structures that describe family relationships such
as kinship and identity-by-descent, which can be used to model family data
in mixed effects models, such as in the coxme function. Also includes a tool
for pedigree drawing which is focused on producing compact layouts without
intervention. Recent additions include utilities to trim the pedigree object
with various criteria, and kinship for the X chromosome.
