Usage

	chromosome2integer(chrom)
        integer2chromosome(intChrom)

Arguments

intChrom	An integer vector with values 1-25 possible

Details

This is useful when sorting SNPs in an object by chromosome and physical position – ensures that the sorting is done in the same way for different objects.
