译者：生物统计家园网 机器人LoveR
描述----------Description----------
Class and constructor for data-driven filter objects that selects high-density regions in two dimensions.
类和构造的数据驱动filter对象，选择在两个方面的高密度区域。
用法----------Usage----------
curv2Filter(x, y, filterId="defaultCurv2Filter", bwFac=1.2,
gridsize=rep(151, 2))
参数----------Arguments----------
参数：x,y
Characters giving the names of the measurement parameter on which the filter is supposed to work on. y can be missing in which case x is expected to be a character vector of length 2 or a list of characters.
字符给予过滤器应该工作的测量参数的名称。 y可缺少的，在这种情况下x预计是一个长度为2个或一个字符列表的特征向量。
参数：filterId
An optional parameter that sets the filterId slot of this filter. The object can later be identified by this name.
一个可选参数，设置filterId此过滤器的插槽。对象可以在以后确定了这个名字。
参数：bwFac, gridsize
Numerics of length 1 and 2, respectively, used to set the bwFac and gridsize slots of the object.
数字，长度为1和2，分别用于设置bwFac和gridsize对象的插槽。
Details
详情----------Details----------
Areas of high local density in two dimensions are identified by detecting significant curvature regions. See <CITE>Duong, T. and Cowling, A. and Koch, I. and Wand, M.P., Computational Statistics and Data Analysis 52/9, 2008</CITE> for details. The constructor curv2Filter is a convenience function for object instantiation. Evaluating a curv2Filter results in potentially multiple sub-populations, an hence in an object of class multipleFilterResult. Accordingly, curv2Filters can be used to split flow cytometry data sets.
局部密度高的区域，在两个方面确定检测重大曲率区域。详情请参阅<CITE>平阳，T.和整流罩，A.和科赫，一和魔杖，国会议员，统计计算和数据分析52/9，2008 </引用>。构造curv2Filter是一个对象实例化的便利功能。评估潜在的多个子种群的因此，在一个对象类curv2FiltermultipleFilterResult结果。因此，curv2Filters可以用来分裂流式单元仪的数据集。
值----------Value----------
Returns a curv2Filter object for use in filtering flowFrames or other flow cytometry objects.
使用过滤curv2Filters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("curv2Filter", ...) or using the constructor curv2Filter. The constructor is the recommended way of object instantiation:
对象可以创建检测形式new("curv2Filter", ...)或使用的构造curv2Filter。构造函数是对象实例的推荐方式：
方法----------Methods----------
%in% signature(x = "flowFrame", table = "curv2Filter"): The workhorse used to evaluate the filter on data. This is usually not called directly by the user, but
在％signature(x = "flowFrame", table = "curv2Filter")：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 = "curv2Filter"): Print
显示signature(object = "curv2Filter")：打印
注意----------Note----------
See the documentation in the flowViz package for plotting of curv2Filters.

举例----------Examples----------
## Loading example data[＃载入数据为例]
dat <- read.FCS(system.file("extdata","0877408774.B08",
package="flowCore"))
## Create directly. Most likely from a command line[＃直接创建。最有可能从一个命令行]
curv2Filter("FSC-H", "SSC-H", filterId="myCurv2Filter")
## To facilitate programmatic construction we also have the following[＃为了便于我们也有以下的纲领性建设]
c2f <- curv2Filter(filterId="myCurv2Filter", x=list("FSC-H", "SSC-H"),
bwFac=2)
c2f <- curv2Filter(filterId="myCurv2Filter", x=c("FSC-H", "SSC-H"),
bwFac=2)
## Filtering using curv2Filter[＃过滤使用curv2Filter]
fres <- filter(dat, c2f)
fres
summary(fres)
names(fres)
## The result of curv2 filtering are multiple sub-populations[＃curv2过滤的结果是多个子种群]
## and we can split our data set accordingly[＃我们可以分裂我们的数据进行相应的设置]
split(dat, fres)
## We can limit the splitting to one or several sub-populations[＃我们可以限制一个或几个子群体的分裂]
split(dat, fres, population="rest")
split(dat, fres, population=list(keep=c("area 2", "area 3")))
curv2Filter("FSC-H", "SSC-H", filterId="test filter")
