    ## S4 method for signature 'GRanges'
    SnpGRanges(object, isSnp)

### Arguments

`object` | A `GRanges` object
`isSnp` | A logical vector. Each genomic interval in the `GRanges` container corresponds to a marker on the genotyping array. `isSnp` is FALSE for nonpolymorphic markers such as those included on the Affymetrix 6.0 chips.
`...` | ignored

### Slots

`elementMetadata`

  a `SnpDataFrame`
