描述----------Description----------
Generic function to test whether a given object (usually a point pattern or something related to a point pattern) has “marks” attached to the points which classify the points into several types.
通用函数来测试一个给定的对象(通常是一个点的图案或阵列点有关的东西)“标记”分类分为好几种类型的点。
用法----------Usage----------
is.multitype(X, ...)
参数----------Arguments----------
参数:X
Object to be inspected
被检查的对象
参数:...
Other arguments.
其他参数。
Details
详细信息----------Details----------
“Marks” are observations attached to each point of a point pattern. For example the longleaf dataset contains the locations of trees, each tree being marked by its diameter; the amacrine dataset gives the locations of cells of two types (on/off) and the type of cell may be regarded as a mark attached to the location of the cell. Other objects related to point patterns, such as point process models, may involve marked points.
“标志”是连接到每个点的点模式的意见。例如longleaf数据集包含的树木的位置,它的直径被标记每个树;amacrine数据集给出了两种类型的单元(开/关)的位置和类型的单元可以是视为连接到的小区的位置的标记。其他相关的对象,以点模式,如点过程模型,可能会涉及标记的点。
This function tests whether the object X contains or involves marked points, and that the marks are a factor.
此功能测试是否对象X包含或涉及标记的点,并且该标记是一个因素。
For example, the amacrine dataset is multitype (there are two types of cells, on and off), but the longleaf dataset is not multitype (the marks are real numbers).
例如,amacrine数据集是多类型(有两种类型的单元,开启和关闭),但longleaf的数据集多类型(该商标是实数)。
This function is generic; methods are provided for point patterns (objects of class "ppp") and point process models (objects of class "ppm").
此功能是通用的方法提供了点模式(对象类"ppp")和点过程模型(对象类"ppm")。
值----------Value----------
Logical value, equal to TRUE if X is multitype.
逻辑值,等于TRUE如果X是多类型。
