LDheatmapData {LDheatmap}R Documentation

Example data set for LDheatmap

Description

HapMap.dat: genotypes on 15 SNPs for 60 people

distance: Physical map positions of the 15 SNPs in HapMap.dat

Usage

data(LDheatmapData)

Format

HapMap.dat: A dataframe of SNP genotypes. Each row represents an individual. Each column represents a SNP.

distance: a vector of integers, representing SNP physical map locations on the chromosome.

Details

Data on SNPs with minor allele frequency greater than 5% from a 9kb region of chromosome 7 (base positions 126273659 through 126282556 from release 7 of the International HapMap Project). Genotypes from 30 parent-offspring trios (both parents, one offspring) were obtained. The 30 trios are taken from the so-called CEPH families, a set of multi-generational Caucasian families from Utah. From this set of 90 people, 60 parents were extracted.
