Description Usage Arguments References See Also Examples

View source: R/cmst.R

Description

Perform joint QTL mapping for phenotypes with marginal LOD peak positions higher than LOD threshold and within set distance of each other

Usage

1
2
GetCommonQtls(cross, pheno1, pheno2, thr = 3, peak.dist = 5,
  addcov1 = NULL, addcov2 = NULL, intcov1 = NULL, intcov2 = NULL)

Arguments

cross

object of class cross

pheno1

first phenotype column number or character string name

pheno2

second phenotype column number or character string name; if more than one, then all phenotypes will be tested against pheno1

thr

LOD threshold

peak.dist

maximal peak distance to be considered the same peak (in cM)

addcov1, addcov2

additive covariates for first and second phenotype, respectively

intcov1, intcov2

interactive covariates for first and second phenotype, respectively
