retrieveLD: Retrieve SNP pairwise LD from locuscompare database
Description
SNP pairwise lD are calculated based on 1000 Genomes Project Phase 3 version 5.
For storage-efficiency, the output will only include SNPs with r2 > 0.2 with the input SNP.
Usage
retrieveLD(chr, snp, population)
Value
A data.frame object.
Arguments
chr
(string) Chromosome name. e.g. '22'. Notice that the name should not contain 'chr'.
snp
(string) SNP rsID.
population
(string) One of the 5 popuations from 1000 Genomes: 'AFR', 'AMR', 'EAS', 'EUR', and 'SAS'.
