Ranges on a Genome
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”).
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)
.
