Examples

library("sim1000G")

examples_dir = system.file("examples", package = "sim1000G")
vcf_file = file.path(examples_dir, "region.vcf.gz")

vcf = readVCF( vcf_file, maxNumberOfVariants = 100 ,
               min_maf = 0.12 ,max_maf = NA)

generateUniformGeneticMap()

startSimulation(vcf, totalNumberOfIndividuals = 200)

ped1 = newNuclearFamily(1)

v = computePairIBD12(1, 3)

cat("IBD1 of pair = ", v[1], "\n");
cat("IBD2 of pair = ", v[2], "\n");
