addmarker: Add a marker to a cross

In qtl: Tools for Analyzing QTL Experiments

Add a marker to a cross

Description

Add a marker to a cross object.

Usage

addmarker(cross, genotypes, markername, chr, pos)

Arguments

cross	An object of class cross. See read.cross for details.
genotypes	Vector of numeric genotypes.
markername	Marker name as character string.
chr	Chromosome ID as character string.
pos	Position of marker, as numeric value.

Details

Use this function with caution. It would be best to incorporate new data into a single file to be imported with read.cross.

But if you have genotypes on one or two additional markers that you want to add, you might load them with read.csv and incorporate them with this function.

Value

The input cross object with the single marker added.
