genoCombinations {pedprobr}

Genotype combinations

Description

Returns the possible genotype combinations in a pedigree, given partial marker data. This function is mainly for internal use.

Usage

genoCombinations(x, partialmarker = x$MARKERS[[1]], ids, make.grid = TRUE)

Arguments

x

a ped() object.

partialmarker

a marker() object compatible with x.

ids

a vector with ID labels of one or more pedigree members.

make.grid

a logical indicating if the result should be simplified to a matrix.

Value

If make.grid = FALSE (the default) the function returns a list of integer vectors, one vector for each element of ids. Each integer represents a genotype, in the form of a row number of the matrix allGenotypes(n), where n is the number of alleles of the marker.

If make.grid = TRUE, the Cartesian product of the vectors is taken, resulting in a matrix with one column for each element of ids.
