用法----------Usage----------
ABalt = c('two.sided', 'less', 'greater'),
Walt = c('two.sided', 'less', 'greater'),
参数----------Arguments----------
参数：DF
a data frame containing (at least) these variables: Series (a factor), Distance, Aim.X, Aim.Ydefining point of aim, Point.X, and Point.Y defining the bullet holes.

参数：plots
a logical value indicating whether diagrams should be shown.

参数：xyTopLeft
a logical value indicating whether the origin of the absolute coordinate system is in the top-left corner. This is the default for data exported by OnTarget PC/TDS.
一个逻辑值，该值指示是否是在左上角的绝对坐标系的原点。这是默认情况下，导出的数据由的ONTARGET PC / TDS。
参数：ABalt
a character string indicating the hypothesis for the Ansari-Bradley-Test for equal variances. Only used when exactly 2 groups are compared.
一个字符串，表示安萨里 - 布拉德利试验的方差相等的假设。仅只有2组进行比较时使用。
参数：Walt
a character string indicating the hypothesis for the Wilcoxon-Rank-Sum-Test for equality of average distance to group center (equivalent to the Mann-Whitney-U-Test). Only used when exactly 2 groups are compared.
一个字符串表示的Wilcoxon秩森平等的平均距离中心组（相当于采用Mann-Whitney U-测试）测试的假设。仅只有2组进行比较时使用。
参数：conversion
how to convert the measurement unit for distance to target to that of the (x,y)-coordinates in MOA calculation. See getMOA.
如何转换的测量单元，用于与目标距离的（x，y）的坐标计算中氧化锌避雷器。见getMOA。

详细信息----------Details----------
OnTarget PC/TDS' Group variable identifies groups just within one file, whereas factor Series is taken to number groups also across different original files. If you only have one original file, you can just copy variable Groups to Series in your data frame. <br> <br> In addition to the numerical results listed below, this function produces the following diagrams:
的ONTARGET PC / TDSGroup变量确定群体只是在一个文件中，而因素Series数组还可以在不同的原始文件。如果你只有一个原始文件，你可以复制变量Groups到Series的数据框。此外<br> <br>在下面列出的数值结果，此功能会产生以下图表：
a scatterplot showing all groups, as well as their respective center and 50%-confidence ellipse
散点图显示所有的群体，以及他们各自的中心和50％的信心椭圆形
a scatterplot showing all groups, as well as their respective minimum bounding box, minimum enclosing circle, and maximum group spread
散点图显示所有的群体，以及他们各自的最小边界框，最小封闭圆的，和最大群体蔓延
a scatterplot showing all groups, as well as their respective minimum enclosing circle and circle with average distance to center
散点图显示所有的组，以及它们各自的最低封闭圆和圆的平均距离中心
