scoreU-methods: Compute the Uniformness(U) score

In selectSNPs: Optimal Selection of SNPs Using a Unified Local Function

Description

This function computes the (U) scores, which measures the uniformness of all the markers on one or more chromsoomes.

Usage

scoreU(object, ...)

## S4 method for signature 'Chrom'
scoreU(object)

## S4 method for signature 'Map'
scoreU(object, chrom)

Arguments

object	An input object, which can be a vector of map position, a Chrom object, or a Map object.
...	Extra input parameters, as needed.
chrom	Names of the chromosomes for which the U score is to be computed; Optional.

Value

The computed U score of the input object.
