Class "UCSCTrackModes"
Description
A vector of view modes ("hide", "dense", "full", "pack", "squish") for each track in a UCSC view.
Objects from the Class
Objects may be created by calls of the form
ucscTrackModes(object =
character(), hide = character(), dense = character(), pack = character(),
squish = character(), full = character())
,
where object
should be a character vector of mode names (with
its names
attribute specifying the corresponding track names).
The other parameters should contain track names that override the
modes in object
. Later parameters override earlier ones, so,
for example, if a track is named in hide
and full
,
it is shown in the full view mode.
Slots
.Data
:Object of class
"character"
holding the modes ("hide", "dense", "full", "pack", "squish"), with itsnames
attribute holding corresponding track names.labels
:Object of class
"character"
holding labels (human-readable names) corresponding to each track/mode.
Extends

, from data part.
Class "vector"
, by class "character", distance 2.
Methods
trackNames(object)
Gets the names of the visible tracks (those that do not have mode "hide").
trackNames(object) <- value
Sets the names of the visible tracks. Any tracks named in
value
are set to "full" if the are currently set to "hide" in this object. Any tracks not invalue
are set to "hide". All other modes are preserved.object[i]
Gets the track mode of the tracks indexed by
i
, which can be any type of index supported by character vector subsetting. Ifi
is a character vector, it indexes first by the internal track IDs (thenames
on.Data
) and then by the user-level track names (thelabels
slot).object[i] <- value
Sets the track modes indexed by
i
(in the same way as inobject[i]
above) to those specified invalue
.
