详细信息----------Details----------
An object of class popn records the locations of a set of individuals, together with ancillary data such as their sex. Often used for a realisation of a spatial point process (e.g. homogeneous Poisson) with known density (intensity). Locations are stored in a data frame with columns "x" and "y".
一种的类popn的对象记录的位置的一组个体,连同辅助数据,如他们的性别。通常用于一个实现的空间点过程(如齐次泊松)与已知的密度(强度)。的位置都存储在一个数据框中的列的“x”和“y”。
A popn object has attributes
Apopn对象的属性
The number of rows in covariates must match the length of x and y. See sim.popn for more information on Ndist and model2D.
在covariates的行数必须符合的长度x和y。见sim.popn的更多信息,Ndist和model2D。
注意----------Note----------
The popn class is used only occasionally: it is not central to spatially explicit capture recapture.
popn类只是偶尔使用,它不是空间显式捕获夺回。
