Swedish Pines Point Pattern
The data give the locations of pine saplings in a Swedish forest.
data(swedishpines)
An object of class "ppp"
representing the point pattern of tree locations
in a rectangular plot 9.6 by 10 metres.
Cartesian coordinates are given in decimetres (multiples of 0.1 metre)
rounded to the nearest decimetre.
Type rescale(swedishpines) to get an equivalent dataset
where the coordinates are expressed in metres.
See ppp.object for details of the format of a
point pattern object.
