In qtl: Tools for Analyzing QTL Experiments

Pull out the results of the Viterbi algorithm from a cross

Description

Pull out the results of argmax.geno from a cross as a matrix.

Usage

pull.argmaxgeno(cross, chr, include.pos.info=FALSE, rotate=FALSE)

Arguments

cross	An object of class cross. See read.cross for details.
chr	Optional vector indicating the chromosomes to consider. This should be a vector of character strings referring to chromosomes by name; numeric values are converted to strings. Refer to chromosomes with a preceding - to have all chromosomes but those considered. A logical (TRUE/FALSE) vector may also be used.
include.pos.info	If TRUE, include columns with marker name, chromosmoe ID, and cM position. (If include.pos.info=TRUE, we take rotate=TRUE.)
rotate	If TRUE, return matrix with individuals as columns and positions as rows. If FALSE, rows correspond to individuals.

Value

A matrix containing numeric indicators of the inferred genotypes. Multiple chromosomes are pasted together.
