描述----------Description----------
An implementation of BrowserSession
执行BrowserSession的
类的对象----------Objects from the Class----------
Objects can be created by calls of the form browserSession("ucsc", url = "http://genome.ucsc.edu/cgi-bin", ...). The arguments in ... correspond to libcurl options, see getCurlHandle. Setting these options may be useful e.g. for getting past a proxy.
创建对象可以通过检测的形式browserSession("ucsc", url = "http://genome.ucsc.edu/cgi-bin", ...)。 ...对应libcurl的选项参数，见getCurlHandle。设置这些选项可能是有用的例如让过去的代理。
插槽----------Slots----------
url: Object of class "character" holding the
url：Object类的"character"举行
hguid: Object of class "numeric" holding the
hguid：Object类的"numeric"举行
views: Object of class "environment" containing a list stored under the name "instances". The list holds the instances of
views：Object类的"environment"的名义下的“实例”存储列表。列表中持有的实例

Class "BrowserSession", directly.
类"BrowserSession"，直接。
方法----------Methods----------
range(object), track = trackNames(object), ...)</dt> Creates a BrowserView of range with visible tracks specified by track. track may be an instance of UCSCTrackModes. Arguments in ... should match parameters to a ucscTrackModes method for creating a UCSCTrackModes instance that will be merged with and
范围（对象），轨道= trackNames（对象），...）</代码> </ DT>创建一个BrowserViewrangetrack指定可见的轨道。 track可能UCSCTrackModes实例。 ...参数应符合参数ucscTrackModesUCSCTrackModes实例创建的方法，将合并
browserViews(object) Gets the
browserViews（对象）获取
range(x, asRangedData = TRUE) Gets the GRanges last displayed in this session. Set asRangedData
range（X，asRangedData = TRUE）获取GRanges最后显示在本次会议。设置了asRangedData
genome(x) Gets the genome identifier of the session,
genome(x)获取会议的基因组标识符，
seqinfo Gets the Seqinfo object with the lengths of the chromosomes in the currenet genome. No circularity information is available.
seqinfo获取与在currenet基因组染色体的长度Seqinfo对象。没有圆信息。
range(x) <- value Sets value, usually a GRanges object or RangesList, as the range of session x. Note that this setting only lasts until a view is created or manipulated. This mechanism is useful, for example, when treating the UCSC
range(x) <- value设置value，通常是GRanges对象或RangesList，会议x的范围。请注意，此设置只持续到一个视图创建或操纵。这种机制是有益的，例如，当治疗的UCSC
Sets the genome identifier on the range of session x.
设置会议x范围内的基因组标识符。
Gets the sequence in range and track.
获取range和track序列。
Loads a track, stored under name and formatted as format. The "auto" format resolves to "bed" for qualitative data. For quantitative data, i.e., data with a numeric score column, "wig" or "bedGraph" is chosen, depending on how well the data compresses into wig. The arguments in ... are passed on to export.ucsc, so they could be slots in a TrackLine subclass (and thus specify visual attributes like color) or parameters to pass on to the export function for format.
载入轨道，存储下name和format格式化。 “自动”格式解析“床”的定性数据。对于定量数据，即，数字score列，“假发”或“bedGraph”的数据选择，取决于如何做好数据假发压缩。在参数...export.ucsc，所以他们可能是插槽TrackLine子类（因此指定的视觉属性，如颜色）或参数传递给出口功能format。
Retrieves a RangedData with features in range from track named name. Some built-in tracks have multiple series, each stored in a separate database table. A specific table may be retrieved by passing its name in the table parameter. See tableNames for a way to list the available tables.
检索RangedData名为range轨道功能与name。一些内置的曲目有多个系列，每个存储在一个单独的数据库表。可检索一个特定的表，通过它的名字table参数。看到tableNames的方式来列出可用的表。
trackNames(object) Gets the
trackNames（对象）获取
ucscTrackModes(object) Gets the
ucscTrackModes（对象）获取
