Converts a gff formated data.frame into a GenomicRanges object. The GenomicRanges object needs to be properly formated for the function to work.

1	gffToGRanges(gff.file, filter = NULL, zero.based = FALSE, ensembl = FALSE)

`gff.file`	path to a gff formatted file. The file can end in `.gz`, `.bz2`, `.xz`, or `.zip` and/or start with `http://` or `ftp://`. If the file is not compressed it can also start with `https://` or `ftps://`.
`filter`	a character designating which elements to retain from the gff file (e.g. exon, CDS, ...)
`zero.based`	`boolean` whether the coordinates are 0 or 1 based. 0 is the default
`ensembl`	`boolean` if TRUE, add the chr prefix to seqlevels. FALSE by default
