Class "circularPlot": Fixed-area Circular Plots
“circularPlot类”：固定区域循环图

描述----------Description----------
A subclass of "ArealSampling" that can be used to create fixed-area circular plot objects for use in sampling surface simulations.
的一个子类的“ArealSampling”可以用来建立固定面积的圆形地积对象，用于采样表面模拟。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("circularPlot", ...); however, this is not recommended due to the necessity to have the spatial representation correct. Rather, one should therefore use the circularPlot constructor for this class.
可以创建对象通过调用的形式new("circularPlot", ...)，但不建议这样做的必要性有正确的空间表述。相反，人们应该使用circularPlot构造这个类。
插槽----------Slots----------
In addition to those slots in class "ArealSampling," the following are defined...
在除了类“ArealSampling这些插槽中，”下面的定义...
radius: Object of class "numeric": The fixed-plot radius in the correct units. For "English" units, this
radius：对象类"numeric"：半径在正确的单位的固定图。对于“英语”的单位，
area: Object of class "numeric": The area of
area：类的对象"numeric"：面积
perimeter: Object of class "SpatialPolygons": The "SpatialPolygons" object corresponding to the perimeter of the
perimeter：类的对象"SpatialPolygons"："SpatialPolygons"对象，对应的周长
location: Object of class "SpatialPoints": This is a “SpatialPoints” representation of the location of the object. In the "circularPlot" class, this is the fixed-radius plot center. It will often correspond to the location slot in the "Stem" object under sampling surface simulations. But there are exceptions: for example, under the "standup" method, it will be at the large-end of the log, while under the "chainsaw" method, it will be some point within the “sausage” shaped inclusion zone for protocol 1 in (Gove and
location：类的对象"SpatialPoints"：这是一个“的SpatialPoints”表示对象的位置。在“circularPlot”类，这是固定半径曲线中心。它往往会与“Stem”下采样表面模拟的对象插槽的位置。但也有例外：例如，在“站立”的方法，将大的log，而根据“链锯”的方法，这将是一段内的“香肠”状夹杂点区（戈夫和协议1
spID: Object of class "character": A unique identifier that will be used in the eventual “SpatialPolygons”
spID：类"character"：一个独特的标识符，该标识符将用于最终的“SpatialPolygons对象”
spUnits: Object of class "CRS": A valid string of class “CRS” denoting the spatial units coordinate system (?CRS
spUnits：类的对象"CRS"：一个有效的字符串类“CRS”，表示空间单元协调系统（CRS
