\title{Genetic analysis package}
\description{
As is first reported, it is designed as an integrated package for genetic data
analysis of both population and family data. Currently, it contains functions for
sample size calculations of both population-based and family-based designs, probability
of familial disease aggregation, kinship calculation, statistics in linkage analysis,
and association analysis involving genetic markers including haplotype analysis with or
without environmental covariates. Over years, the package has been developed in-between
many projects hence also in line with the name (gap).

We have incorporated functions for a wide range of problems as shown below.
