“circularPlot”对象在包工程的方法
译者:生物统计家园网 机器人LoveR
描述----------Description----------
There is currently only one method based on the circularPlot generic that is used for object
目前只有一个方法用于对象的circularPlot通用的基础上,
方法----------Methods----------
This method takes the plot radius as the signature argument along
该方法以图的特征参数沿半径
usage...
使用...
radius: The fixed-plot radius in the correct units. For "English" units, this would be feet, for "metric" units, meters.
radius:的固定图半径的单位正确的。 “英语”的单位,这将是脚,“公制”单位,米。
units: Either “English” or “metric”. These must be conformable with the projection in spUnits.
units:“英语”或“公制”。这些都必须按照spUnits投影。
spUnits: A valid CRS object specifying the Coordinate Reference System. This defaults to NA, which means you want to use your own user-defined system, say for a sample plot located in the field.
spUnits:有效的CRS对象指定的坐标参考系统。这是预设NA,这意味着你要使用自己的用户定义的系统,在外地一个样地说。
centerPoint: The location of the center of the fixed-area plot in the appropriate spatial units. This should be a numeric vector of length 2 with names "x" and "y".
centerPoint:位置,在适当的空间单元的中心的固定面积的图。这应该是一个数值向量的长度为2的名称的“x”和“y”。
description: A character vector description of the tract.
description:一个字符向量描述的道。
nptsPerimeter: The number of points that will compose the spatial perimeter of the object. Note that the final result will always be one more point than requested in order to close the polygon.
nptsPerimeter:的点的数量,将组成该对象的空间周长。请注意,最后的结果将始终是一个多点,比要求以关闭多边形。
spID: Each object should have its own unique identifier that is used in constructing the Polygons object for the perimeter. This becomes very important when combining individual plots into a population. If nothing is supplied, a random ID is generated.
spID:每个对象都应该有它自己唯一的标识符,用于的周边建设Polygons对象的。结合时,个别图成人口,这已成为非常重要的。如果没有被提供时,生成随机ID。
