Convert genotypic data in character to number for training models

Description

This function help users to transform genetic matrix from character format to numeric format. AA-0, Aa-1, aa-2, A is major allele and a is minor allele.

Usage

transHapmap2numeric(G)

Arguments

G	Genetic matrix of character, row represents sample and column represents SNP.

Examples

## Not run! 
## load hapmap data (genomic data) of MZ hybrids
data(MZ)

## pre-process for input of transHapmap2numeric 
rownames(MZ) <- MZ[,1]
MZ <- MZ[,-c(1:11)]
MZ.t <- t(MZ)

## conversion
MZ.n <- transHapmap2numeric(MZ.t)
dim(MZ.t)
