## Ranges on a Genome

### Description

Genomic coordinates are often specified in terms of a genome identifier, chromosome name, start position and end position. The `rtracklayer` package adds convenience methods to `IntegerRangesList` for the manipulation of genomic ranges. The spaces (or names) of `IntegerRangesList` are the chromosome names. The `universe` slot indicates the genome, usually as given by UCSC (e.g. “hg18”).

### Accessors

In the code snippets below, `x` is a `IntegerRangesList` object.

  `chrom(x), chrom(x) <- value`: Gets or sets the chromosome names for `x`. This is an alias for `names(x)`.
