bcMVNmtQTL {rmtQTL}R Documentation

Multivariate normal (MVN) distribution based multi-trait QTL analysis.

Description

This function calculates the LOD (log of odds) for multi-trait QTL analysis using multivariate normal distribution.

Usage

bcMVNmtQTL(inData, phenoCols=1, Chrs)

Arguments

inData

Input data set along with genotype probabilities for multi-trait QTL analysis.

phenoCols

Column numbers in the phenotype matrix which should be used in the analysis.

Chrs

Vector of chromosome number(s) for which LOD scores should be calculated.

Value

It will return a dataframe with the values of chromosome number, marker position (in cM) and LOD statistic for multi-trait QTL mapping.
