描述----------Description----------

The groupedData object is summarized by the values of the displayLevel grouping factor (or the combination of its values and the values of the covariate indicated in preserve, if any is present). The collapsed data is used to produce a new groupedData object, with grouping factor given by the displayLevel factor, which is plotted using the appropriate plot method for groupedData objects with single level of grouping.
groupedData对象总结displayLevel分组因子值（或它的价值观和协值的组合，在preserve，如有存在表示）。倒塌的数据被用来生产groupedData因素，这是适当displayLevel方法使用单plot对象绘制的分组因素的一个新的groupedData对象，分组的水平。


用法----------Usage----------


## S3 method for class 'nmGroupedData'
plot(x, collapseLevel, displayLevel, outer, inner,
    preserve, FUN, subset, key, grid, ...)



参数----------Arguments----------

参数：x
an object inheriting from class nmGroupedData, representing a groupedData object with multiple grouping factors.  
对象类继承nmGroupedData，groupedData多个分组因素的对象。


参数：collapseLevel
an optional positive integer or character string indicating the grouping level to use when collapsing the data. Level values increase from outermost to innermost grouping. Default is the highest or innermost level of grouping.  
一个可选的正整数或字符串，指示分组级别的数据崩溃时使用。级别值增加从最外层到最内层的分组。默认是分组的最高或最内层的水平。


参数：displayLevel
an optional positive integer or character string indicating the grouping level to use for determining the panels in the Trellis display, when outer is missing. Default is collapseLevel.  
一个可选的正整数或字符串显示分组级别用于确定在格子显示面板，当outer失踪。默认collapseLevel。


参数：outer
an optional logical value or one-sided formula, indicating covariates that are outer to the displayLevel grouping factor, which are used to determine the panels of the Trellis plot. If equal to TRUE, the displayLevel element attr(object, "outer") is used to indicate the  outer covariates. An outer covariate is invariant within the sets of rows defined by the grouping factor.  Ordering of the groups is done in such a way as to preserve adjacency of groups with the same value of the outer variables. Defaults to NULL, meaning that no outer covariates are to be used.   
一个可选的逻辑值或片面的公式，表明变项，外displayLevel分组因素，这是用来确定的网格图板的。如果等于TRUE，displayLevel元素attr(object, "outer")用来指示外协变量。外协变量是不变的定义分组因素的行集内。是在这样一种方式，保持与外部变量的值相同组邻接排列的团体。 NULL默认值，这意味着要使用无外协变量。


参数：inner
an optional logical value or one-sided formula, indicating a covariate that is inner to the displayLevel grouping factor, which is used to associate points within each panel of the Trellis plot. If equal to TRUE, attr(object, "outer") is used to indicate the inner covariate. An inner covariate can change within the sets of rows defined by the grouping  factor. Defaults to NULL, meaning that no inner covariate  is present.     
一个可选的逻辑值或片面的公式，表明displayLevel分组因素，这是用来在每个面板的格子图关联点是内在的协变量。如果等于TRUE，attr(object, "outer")用来表示内部协变量。一种内在的协变量定义分组因素的行集内可以改变。 NULL默认值，即没有内在的协变量是目前。


参数：preserve
an optional one-sided formula indicating a covariate whose levels should be preserved when collapsing the data according to the collapseLevel grouping factor. The collapsing factor is obtained by pasting together the levels of the collapseLevel grouping factor and the values of the covariate to be preserved. Default is NULL, meaning that no covariates need to be preserved.  
根据collapseLevel分组因素的数据崩溃时，应予以保留一个可选的双面公式表示协变量的水平。崩溃的因素，得到粘贴collapseLevel分组因素和协要保留的值的水平。默认是NULL，这意味着没有需要保留的协变量。


参数：FUN
an optional summary function or a list of summary functions to be used for collapsing the data.  The function or functions are applied only to variables in object that vary within the groups defined by collapseLevel.  Invariant variables are  always summarized by group using the unique value that they assume within that group.  If FUN is a single function it will be applied to each non-invariant variable by group to produce the summary for that variable.  If FUN is a list of functions, the names in the list should designate classes of variables in the data such as ordered, factor, or numeric.  The indicated function will be applied to any non-invariant variables of that class.  The default functions to be used are mean for numeric factors, and Mode for both factor and ordered.  The Mode function, defined internally in gsummary, returns the modal or most popular value of the variable.  It is different from the mode function that returns the S-language mode of the variable.
一个可选的汇总函数或汇总函数的列表将用于折叠的数据。函数或功能只适用于在变量object，在collapseLevel定义组不同。不变的变量总是总结组采用独特的价值，他们在该组承担。 FUN如果是一个单一的功能，将应用于组每个非不变的变量，该变量为生产总结。如果FUN是一个功能列表，列表中的名称应指定变量的类的数据，如ordered，factor或numeric。指定的函数将被应用到这个类的任何非不变的变量。要使用的默认功能是mean数字因素，Mode都factor和ordered。 Mode函数内部定义在gsummary，返回变量的模式或最流行的价值。它mode函数返回变量的S-语言模式是不同的。


参数：subset
an optional named list. Names can be either positive integers representing grouping levels, or names of grouping factors. Each element in the list is a vector indicating the levels of the corresponding grouping factor to be used for plotting the data. Default is NULL, meaning that all levels are used.  
一个可选的命名列表。名称可以是正整数，代表分组级别，或分组因素的名称。列表中的每个元素是一个矢量被用来绘制数据表明相应的分组因素水平。默认是NULL，这意味着各级使用。


参数：key
an optional logical value, or list. If TRUE, a legend is included at the top of the plot indicating which symbols (colors) correspond to which prediction levels. If FALSE, no legend is included. If given as a list, key is passed down as an argument to the trellis function generating the plots (xyplot). Defaults to TRUE.
一个可选的逻辑值或列表。 TRUE如果，传说是在顶部的指示符号（颜色），预测水平相对应的图。如果FALSE，没有传说中已包含。如果给出一个列表，key流传下来作为一个参数trellis（xyplot）函数生成的图。 TRUE默认。


参数：grid
an optional logical value indicating whether a grid should be added to plot. Default is TRUE.
一个可选的逻辑值，该值指示网格是否应该被添加到图。默认TRUE。


参数：...
optional arguments passed to the Trellis plot function.
可选参数传递给格子绘图功能。


值----------Value----------

a Trellis display of the data collapsed over the values of the collapseLevel grouping factor and grouped according to the displayLevel grouping factor.
格子的数据显示倒塌了collapseLevel分组因素的值和按displayLevel分组因素。
