`chrom` | A one or 2 letter character string (e.g, "1", "X", "Y", "MT", "XY")
`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.
