bsnR:

#' Simulated family pedigrees. 
#'
#' A dataset containing (possibly duplicated) family pedigrees, 
#' with each family consisting of a reported 'self' individual
#' and various cancer risk indicators/status, as well as a 
#' pseudo-random collection of reported family members
#' and their associated indicators. Allele sharing between generations
#' follow basic Mendelian inheritance with parameters provided by
#' BayesMendel.
