Could you explain why the HWETriangBF2 is returining completely different
values of Bayes Factor??

R genetics package now available
...classes and methods for creating, representing, and
manipulating genotypes (unordered allele pairs) and haplotypes (ordered
allele pairs). Genotypes and
haplotypes can be annotated with chromosome, locus, gene, and marker
information. Utility functions compute genotype and allele frequencies, flag
homozygotes or heterozygotes, flag allele carriers
of certain alleles, count the number of a specific allele carried by an
individual, extract one or both alleles, estimate and generate confidence
intervals for measures of single-marker disequlibrium, and test for
departure from Hardy-Weinberg equilibrium....

genotype analysis
...currently totally confused by the
many R packages available to do such analysis.
Here is my case: I've got a list of genes, and a number of
case-control population pairs, and for each population and gene, the
various genotypes that have been found. I've got both aggregate data
(ex. gene1: homozygote wildtype: 201, heterozygote mutation carrier:
34, homozygote mutation carrier: 5) and per-gene data (i.e. for gene1
a list of e.g. "V/V", "V/I", "II" etc).
The question asked is whether there is a difference in the mutation
pattern between the case and the control gr...

help needed for HWE.exact in library "genetics"
Hi,
I have a genotype data for both case and controls and would like to calculate the HW p-value. However, since the number of one genotype is 0, I got wired result. Would someone help me to figure it out? Or confirm it's right? Thanks a lot.
