## Construct a GRanges object from several possible feature-level classes

### Description

Construct a GRanges object from several possible feature-level classes. The conversion is useful for subsequent ranged-data queries, such as `findOverlaps`, `countOverlaps`, etc.

### Usage

    makeFeatureGRanges(object, ...)

### Arguments

`object` | A `gSet`-derived object containing chromosome and physical position for the markers on the array.
`...` | See the `makeFeatureGRanges` method for `GenomeAnnotatedDataFrame`.

### Value

A `GRanges` object.

### Author(s)

R. Scharpf

### Examples

      library(oligoClasses)
    	library(GenomicRanges)
    	library(Biobase)
    	library(foreach)
    	registerDoSEQ()
    	data(oligoSetExample, package="oligoClasses")
    	oligoSet <- oligoSet[chromosome(oligoSet) == 1, ]
      makeFeatureGRanges(oligoSet)
