描述----------Description----------
Class and constructor for 2-dimensional polygonal filter objects.
2维多边形filter对象的类和构造。
用法----------Usage----------
polygonGate(..., .gate, boundaries, filterId="defaultPolygonGate")
参数----------Arguments----------
参数：filterId
An optional parameter that sets the filterId of this gate.
一个可选的参数，设置了这个门filterId。
参数：.gate, boundaries
A definition of the gate. This can be either a list or a named matrix as described below. Note the argument boundaries is deprecated and will go away in the next release.
门的定义。这可以是一个列表或一个名为矩阵如下所述。注意参数的边界已被废弃，将在下一个版本中。
参数：...
You can also directly describe a gate without wrapping it in a list or matrix, as described below.
你也可以直接描述一个门，没有包裹在一个列表或矩阵，如下所述。
Details
详情----------Details----------
Polygons are specified by the coordinates of their vertices in two dimensions. The constructor is designed to be useful in both direct and programmatic usage. It takes either a list or a named matrix with 2 columns and at least 3 rows containing these coordinates. Alternatively, vertices can be given as named arguments, in which case the function tries to convert the values into a matrix.
多边形指定其顶点坐标在两个方面。构造设计，直接和纲领性的使用是有用的。它需要一个列表或一个2列和至少3行包含这些坐标命名的矩阵。另外，顶点可以作为命名的参数，在这种情况下，该函数尝试转换成一个矩阵值。
值----------Value----------
Returns a polygonGate object for use in filtering flowFrames or other flow cytometry objects.
使用过滤polygonGates或其他流式单元仪检测对象返回一个flowFrame对象。

类的对象----------Objects from the Class----------
Objects can be created by calls of the form new("polygonGate", ...) or by using the constructor polygonGate. Using the constructor is the recommended way of object instantiation:
对象可以创建形式new("polygonGate", ...)来电或使用的构造polygonGate。使用构造对象实例的推荐方式：
方法----------Methods----------
%in% signature(x = "flowFrame", table = "polygonGate"): The workhorse used to evaluate the filter on data. This is usually not called directly by the user, but
在％signature(x = "flowFrame", table = "polygonGate")：主力用来评估对数据的过滤器。这通常不是直接调用的用户，但
show signature(object = "polygonGate"): Print
显示signature(object = "polygonGate")：打印

举例----------Examples----------
## Loading example data[＃载入数据为例]
dat <- read.FCS(system.file("extdata","0877408774.B08",
package="flowCore"))
## Defining the gate[＃定义的门]
sqrcut <- matrix(c(300,300,600,600,50,300,300,50),ncol=2,nrow=4)
colnames(sqrcut) <- c("FSC-H","SSC-H")
pg <- polygonGate(filterId="nonDebris", boundaries= sqrcut)
pg
## Filtering using polygonGates[＃过滤使用polygonGates]
fres <- filter(dat, pg)
fres
summary(fres)
## The result of polygon filtering is a logical subset[＃多边形滤波的结果是一个逻辑子集]
Subset(dat, fres)
## We can also split, in which case we get those events in and those[＃我们也可以分裂，在这种情况下，我们得到这些事件和那些]
## not in the gate as separate populations[＃而不是作为单独的种群门]
split(dat, fres)
