描述----------Description----------
A number of clustering methods exist in CAMERA. calcPC is the generic method.
一些聚类方法存在的摄像头。 calcPC是通用的方法。
用法----------Usage----------
calcPC(object, method, ...)
参数----------Arguments----------
参数：object
xsAnnotate-class object
xsAnnotate-class对象
参数：method
Method to use for clustering. See details.
使用聚类方法。查看详情。
参数：...
Optional arguments to be passed along
要通过沿可选参数

详情----------Details----------
This algorithms cluster peaks from a xsAnnotate object into pseudospectra according to a provided distance matrix. Therefore all peaks are transformend into a graph, with peaks as nodes and the value from the distance matrix as edges. Afterwards a graph separation algorithm is applied, which searches in the graph for clusters. See the manpages of the specific clustering algorithms for more information.
这种算法聚类从xsAnnotate对象伪谱峰，根据提供的距离矩阵。因此，所有的山峰都transformend成图，峰值为节点，并作为边缘的距离矩阵值。事后图形分离算法应用，聚类图搜索。有关详细信息，具体的聚类算法，请参阅联机帮助页。
If the xsAnnotate is pregrouped, for example groupFWHM, only the already existing groups will be further processed.
如果是pregrouped xsAnnotate，例如groupFWHM的，只有现有的群体将进一步处理。
The different algorithms that can be used by specifying them with the method argument. For example to use the highly connected subgraphs approach by E. Hartuv, R. Shamir, (1999), one would use: calcPC(object, method="hcs"). This is also the default, see calcPC.hcs.
由他们指定method参数，可以使用不同的算法。例如，使用高度连通子图E. Hartuv·沙米尔（1999）的方法，将使用calcPC(object, method="hcs")。这也是默认情况下，看到calcPC.hcs。
Further arguments given by ... are passed through to the function implementing the method, which are most likely ajc. The parameter ajc is the peak distance matrix.
...给予进一步的论据是通过执行method，这是最有可能的AJC功能。参数AJC是繁忙的距离矩阵。
getOption("BioC")$CAMERA$findPeaks.methods returns a character vector of nicknames for the algorithms available.
getOption("BioC")$CAMERA$findPeaks.methods返回一个特征向量算法的昵称。
The function returns a xsAnnotate object with grouping information, as list of peak indices. They are stored as object@pspectra.
该函数返回1 xsAnnotate对象与分组信息，峰值指数列表。它们存储为对象pspectra。
