sameGenotype: Find markers for which two individuals have the same genotype

Description

Identifies markers for which two individuals have the same (non-missing) genotype. The comparison is done after sorting the genotypes internally.

Usage

sameGenotype(x, ids = typedMembers(x), count = FALSE)

Value

A logical vector with one entry per marker (NA if either genotype is missing). If count = TRUE, the number of TRUE entries.

Arguments

x

A ped object or a list of such. An error is raised if x has no marker data.

ids

A vector of two individual ID labels.

count

A logical. If TRUE, return the number of markers with shared genotype.
