Class "TrackLine"
Description
An object representing a "track line" in the UCSC
format. There are two concrete types of track lines:
BasicTrackLine
(used for most types of tracks) and
GraphTrackLine
(used for graphical tracks). This class
only declares the common elements between the two.
Objects from the Class
Objects can be created by calls of the form new("TrackLine",
...)
or parsed from a character vector track line with
as(text, "TrackLine")
.
But note that UCSC only understands one of the
subclasses mentioned above.
