Internal: compares two pairs of alleles

Description

Used for computation of the genetic distances alleledist.

Usage

  allelepaircomp(allelepair1,allelepair2,method="sum")

Arguments

`allelepair1`	vector of two allele codes (usually characters), or `NA`.
`allelepair2`	vector of two allele codes (usually characters), or `NA`.
`method`	one of `"sum"` or `"geometrical"`.

Value

If method=="sum", number of shared alleles (0, 1 or 2), or NA. If method=="geometrical", 0, 0.5, sqrt(0.5) (in case that one of the allelepairs is double such as in c("A","B"),c("A","A")) or 1, or NA.
