QTLmapping: QTLmapping - QTL mapping method for CTL analysis

Description

Internal QTL mapping method used by the CTL analysis, associates every column in the genotypes with a single phenotype

Usage

QTLmapping(genotypes, phenotypes, phenocol = 1, verbose = TRUE)

Value

vector of LOD scores for each genotype column, for phenotype column phenocol

Arguments

genotypes

Matrix of genotypes. (individuals x markers)

phenotypes

Matrix of phenotypes. (individuals x phenotypes)

phenocol

Which phenotype column(s) should we analyse. Default: Analyse a single phenotype.
