UCSCTrackModes-class {rtracklayer} | R Documentation

## 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 its `names` attribute holding corresponding track names.

`labels`:

  Object of class `"character"` holding labels (human-readable names) corresponding to each track/mode.

### Extends

Class `"character"`, 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 in `value` 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. If `i` is a character vector, it indexes first by the internal track IDs (the `names` on `.Data`) and then by the user-level track names (the `labels` slot).

`object[i] <- value`

  Sets the track modes indexed by `i` (in the same way as in `object[i]` above) to those specified in `value`.
