read.outcross2: Read data from a full-sib progeny (outcrossing populations)

Description

This version implements the read.outcross function in a faster way. Everything else is essentially the same.

Usage

read.outcross2(infile)

Arguments

infile

the name of the input file which contains the data to be read.

Value

An object of class outcross, i.e., a list with the following components:

geno

a matrix with integers indicating the genotypes read for each marker. Each column contains data for a marker and each row represents an individual.

n.ind

number of individuals.

n.mar

number of markers.

segr.type

a vector with the segregation type of each marker, as strings.

segr.type.num

a vector with the segregation type of each marker, represented in a simplified manner as integers, i.e. 1 corresponds to markers of type "A"; 2 corresponds to markers of type "B1.5"; 3 corresponds to markers of type "B2.6"; 4 corresponds to markers of type "B3.7"; 5 corresponds to markers of type "C.8"; 6 corresponds to markers of type "D1" and 7 corresponds to markers of type "D2"

n.phe

the number of traits included in the file

pheno

the name of the phenoytpes

input

the name of the input file.
