getGenotypes: Genotype matrix

Description

Extract the genotypes of specified individuals and markers from a pedigree object, and return them as a character matrix.

Usage

getGenotypes(x, ids = NULL, markers = NULL, sep = "/", missing = "-")

Value

getGenotypes() returns a character matrix with length(ids) rows and length(markers) columns.

Arguments

x

A ped object or a list of such.

ids

A vector of ID labels, or a function operating on x, e.g., typedMembers(). By default (ids = NULL) all individuals are included, also non-genotyped ones.

sep

### A list of pedigrees

s = transferMarkers(x, singleton("s"))
peds = list(x, s)
