halfsibscan {lodplot}R Documentation

Simulation of affected half-sib pair genome scan

Description

Generate results from an affected half-sib pair genome scan

Usage

halfsibscan(N = 100, grid = 1)

Arguments

N is the number of affected half-sib pair families
grid the distance between the (perfectly informative) scan markers

Details

Carried out the appropriate random walk on each chromosome to generate lod scores that would result if there were no trait loci segregating in the pedigrees sampled.

Value

A data frame, containing:

chr the chromosome (1..22, X)
pos the genetic map position on the chromosome
lod the simulated lod score.
