描述----------Description----------
Cell populations of roughly elliptical shape in two-dimensional projections are of huge interest in many flow cytometry applications. This function identifies a single such population, potentially from a mixture of multiple populations.
二维预测大致椭圆形单元群是巨大的利益在许多流式单元仪的应用。此功能标识一个这样的人口，可能从多个人群的混合物。
用法----------Usage----------
lymphGate(x, channels, preselection=NULL, scale=2.5, bwFac=1.3,
filterId="defaultLymphGate", evaluate=TRUE, plot=FALSE, ...)
lymphFilter(channels, preselection=as.character(NULL),
scale=2.5, bwFac=1.3, filterId="defaultLymphFilter")
参数----------Arguments----------
参数：x
An object of class flowSet.
对象类flowSet。
参数：channels
A character vector of length 2 of valid flow parameters in x.
x有效的流动参数2长度的一个特征向量。
参数：preselection
Either NULL, in which case this boils down to fitting a regular norm2Filter, a character scalar giving one of the flow parameters in x, or a named list of numerics specifying the initial rough preselection. The latter gets passed on to rectangleGate, see it's documentation for details.
要么NULL，在这种情况下这可以归结为装修定期norm2Filter给x，或指定的数值计算列表中的流动参数字符标量指定的初始粗糙预选。后者被传递到rectangleGate，看到它的细节的文件。
参数：scale
The scaleFactor parameter that gets passed on to norm2Filter.
scaleFactor参数被传递到norm2Filter。
参数：bwFac
The bandwidth factor that gets passed on to curv1Filter.
带宽的因素传递curv1Filter的。
参数：filterId
A character used as filterId.
字符用作filterId。
参数：evaluate
A logical indicating wether the filter should be resolved (computation of the filterResult and the subset).
应解决的逻辑表示天气的过滤器（filterResult“的子集计算）。
参数：plot
Logical. Produce plots of filter results
逻辑。生产筛选结果图
参数：...
Additional arguments.
额外的参数。

详情----------Details----------
This algorithm does not apply real mixture modelling, however it is able to identify a single elliptical cell population from a mixture of multiple such populations. The idea is to first define a rough rectangular preselection and, in a second step, fit a bivariate normal distribution to this subset only.
这种算法并不适用于真正的混合模型，但它是能够确定一个单一的椭圆形单元人口从多个这样的人口混合。我们的想法是先定义一个粗糙的矩形预选，并在第二个步骤，只适合二元正态分布，这个子集。
Depending on the value of preselection, the initial rough selection is either
对取决于preselection的价值，要么是初步的粗选
NULL: No preselection at all
空：没有在所有的预选
character scalar Preselection based on cells that are positive for a single marker only. This allows for back-gating, for instances by selecting CD4+ T-cells and using this information to back-gate lymphocytes in FSC and SSC. Positive cells are identified using a
字符标预选的基础上，只为一个单一的标记阳性的单元。这使得回门控的情况下，选择CD4+T单元，并使用此信息来FSC和SSC背栅淋巴单元。阳性单元识别使用
a named list of numerics: Preselection by a rectangular gate. The items of the list have to be numerics of length one
命名的数值计算列表：预选由一个长方形大门。列表中的项目必须是一个长度的数值计算
The lymphFilter class and constructor provide the means to treat lymphGates as regular flowCore filters.
lymphFilter类和构造提供的手段对待lymphGates常规flowCore过滤器。
值----------Value----------
A list with items

参数：n2gate
The norm2Filter object.
norm2Filter对象。
参数：n2gateResults

for the lymphGate function. Note that x and n2gateResults are NULL when eval=FALSE.

preselection类character，对象
rectDef: Object of class list, the initial
rectDef：Object类的list，初始
scale: Object of class numeric.
scale类numeric的对象。
bwFac: Object of class numeric.

filterId: Object of class "character", the
filterId类"character"，对象
类的对象----------Objects from the Class----------
Objects can be created by calls of the form new("lymphFilter", parameters, ...) or using the constructor lymphFilter. The constructor is the recommended way of object instantiation.
对象可以创建检测形式new("lymphFilter", parameters, ...)或使用的构造lymphFilter。构造函数是对象实例的推荐方式。
方法----------Methods----------
%in% signature(x = "flowFrame", table = "lymphFilter"): the work horse for doing the actual filtering. Internally, this simply calls the lympghGate
在％signature(x = "flowFrame", table = "lymphFilter")：做实际的过滤工作马。在内部，这只是调用lympghGate

举例----------Examples----------
data(GvHD)
dat <- GvHD[pData(GvHD)$Patient==10]
dat <- transform(dat, "FL4-H"=asinh(`FL4-H`))
lg <- lymphGate(dat, channels=c("FSC-H", "SSC-H"), preselection="FL4-H",scale=1.5)
if(require(flowViz))
xyplot(`SSC-H`~`FSC-H`, dat, filter=lg$n2gate)
## This is using the abstract lymphFilter class instead[＃这是使用而不是抽象lymphFilter类]
lf <- lymphFilter(channels=c("FSC-H", "SSC-H"), preselection="FL4-H")
filter(dat, lf)
