Class "pointRelascopeIZ"
类“pointRelascopeIZ”
译者：生物统计家园网 机器人LoveR
描述----------Description----------
This class holds the inclusion zone definition for the "point relascope" method (Gove et. al, 1999) for sampling down coarse woody debris.
这个类持有纳入区域定义为的“点relascope”方法（戈夫等人，1999），采样粗木质残。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("pointRelascopeIZ", ...). However, this is not recommended because the objects are fairly complex. Instead, one can use the object constructor pointRelascopeIZ to create new objects.
可以创建对象通过调用的形式new("pointRelascopeIZ", ...)。然而，这是不推荐的，因为对象是相当复杂的。相反，一个人可以使用对象的构造函数pointRelascopeIZ创建新的对象。
插槽----------Slots----------
Most of the slots are described in the superclasses (see below), please see their help pages for more information. This class adds a few slots to the "downLogIZ" class specification.
大部分的插槽中描述的超类（见下文），有关详细信息，请参阅其说明页面。这个类增加了几个插槽的的“downLogIZ”级规格。
prs: Object of class "pointRelascope": This supplies the information on the relascope angle, etc., used for
prs：类的对象"pointRelascope"：提供的relascope角度等信息，为
dualCircle: Object of class "matrix": A matrix representation of the dual circle inclusion zone in homogeneous coordinates. This can be manipulated and plotted as desired for
dualCircle：类的对象"matrix"：双圈列入区在齐次坐标矩阵表示的。这可以被操纵，并绘制为所需的
radius: Object of class "numeric": The radius
radius：对象类"numeric"半径：
area: Object of class "numeric": The exact area
area：类的对象"numeric"：确切面积
perimeter: Object of class "SpatialPolygons": This is the
perimeter：类的对象"SpatialPolygons"：是
pgDualArea: Object of class "numeric": This is the area of the dual circle inclusion zone as calculated from the polygon in the perimeter slot using the “SpatialPolygons” object. As such, it is an approximation of the true area of the inclusion zone, which is given in the area slot. This just enables us to see how close the graphic representation is to the real area, and adjust if necessary the number of points defining the
pgDualArea：对象类"numeric"：这是计算双圆列入区从使用“SpatialPolygons”对象的周边槽的多边形的面积。因此，这是一个近似的真实面积列入区，这是考虑在该区域的插槽。这只是使我们能够看到的图形表示是多么接近的实际区域，如果需要的点的数量限定调整
dualCenters: Object of class "matrix" The center points of each of the dual circles as a
dualCenters：作为一个对象类"matrix"该中心的每一个点的双圈
