## Getting browser views

### Description

Methods for creating and getting browser views.

### Usage

      browserView(object, range, track, ...)

### Arguments

`object` | The object from which to get the views.
`range` | The `GRanges` or `IntegerRangesList` to display. If there are multiple elements, a view is created for each element and a `BrowserViewList` is returned.
`track` | List of track names to make visible in the view.
`...` | Arguments to pass to methods

### Methods

The following methods are defined by rtracklayer.

object = "UCSCSession"

  `browserView(object, range = range(object), track = trackNames(object), imagewidth = 800, ...)`: Creates a `BrowserView` of `range` with visible tracks specified by `track`. The `imagewidth` parameter specifies the width of the track image in pixels. `track` may be an instance of `UCSCTrackModes`. Arguments in `...` are passed to `ucscTrackModes` to create the `UCSCTrackModes` instance that will override modes indicated by the `track` parameter.

### Examples

    ## Not run:
      session <- browserSession()
      browserView(session,
                  GRangesForUCSCGenome("hg19", "chr2", IRanges(20000, 50000)))
      ## only view "knownGene" track
      browserView(session, track = "knownGene")
