描述----------Description----------
This method constructs the flowDens object which is used to generate a contour or image plot.
这种方法构造的flowDens对象是用来生成一个轮廓或图像图。
用法----------Usage----------
## S4 method for signature 'flowClust'
density(x, data=NULL, subset=c(1,2), include=1x@K),
npoints=c(100,100), from=NULL, to=NULL)
参数----------Arguments----------
参数:x
Object returned from flowClust or from running filter on a flowFrame object.
从flowClust运行filterflowFrame对象返回的对象。
参数:data
A matrix, data frame of observations, or object of class flowFrame. This is the object on which flowClust or filter was performed. If this argument is not specified, the grid square upon which densities will be computed must be provided (through arguments from and to).
一个矩阵,观测的数据框,或对象类flowFrame。这是上flowClust或filter执行的对象。如果未指定此参数,将计算后,它的密度方格必须提供(通过参数from和to)。
参数:subset
A numeric vector of length two indicating which two variables are selected for the scatterplot. Alternatively, a character vector containing the names of the two variables is allowed if x@varNames is not NULL.
一个长度说明这两个变量的散点图选择两个数字向量。另外,含有两个变量的名称字符向量允许x@varNames如果非NULL。
参数:include
A numeric vector specifying which clusters are included to compute the density values. By default, all clusters are included.
指定一个数值向量包括聚类计算的密度值。默认情况下,所有的聚类都包括在内。
参数:npoints
A numeric vector of size two specifying the number of grid points in x (horizontal) and y (vertical) directions respectively.
指定一个大小两个数字矢量x(水平)和y(垂直)方向分别在格点的数量。
参数:from
A numeric vector of size two specifying the coordinates of the lower left point of the grid square. Note that, if this (and to) is not specified, data must be provided such that the range in the two variables (dimensions) selected will be used to define the grid square.
数字矢量的大小两个指定的坐标方格左边的较低点。需要注意的是,(和to)没有被指定,data必须提供这样的范围中选择两个变量(维度)将被用来定义方格。
参数:to
A numeric vector of size two specifying the co-ordinates of the upper right point of the grid square.
数字矢量的大小两个指定的坐标方格上点右键。
