lansing: Lansing Woods Point Pattern


Locations and botanical classification of trees in Lansing Woods.

The data come from an investigation of a 924 ft x 924 ft (19.6 acre) plot in Lansing Woods, Clinton County, Michigan USA by D.J. Gerrard. The data give the locations of 2251 trees and their botanical classification (into hickories, maples, red oaks, white oaks, black oaks and miscellaneous trees). The original plot size (924 x 924 feet) has been rescaled to the unit square.

Note that the data contain duplicated points (two points at the same location). To determine which points are duplicates, use duplicated.ppp. To remove the duplication, use unique.ppp.





An object of class "ppp" representing the point pattern of tree locations. Entries include

x Cartesian \(x\)-coordinate of tree
y Cartesian \(y\)-coordinate of tree

The levels of marks are blackoak, hickory, maple, misc, redoak and whiteoak. See ppp.object for details of the format of a point pattern object.
