addloctocross {qtl}

Add phenotype location into a cross object

Description

Add phenotype location(s) into a cross object (with eQTL/pQTL studies)

Usage

    addloctocross(cross, locations=NULL, locfile="locations.txt", verbose=FALSE)

Arguments

cross

An object of class cross. See read.cross for details.

locations

R variable holding location information

locfile

load from a file, see the details section for the layout of the file.

verbose

If TRUE, give verbose output
