Japanese Pines Point Pattern
}
\description{
The data give the locations of Japanese black pine saplings
in a square sampling region in a natural forest.
The observations were originally collected by Numata (1961).
These data are used as a standard example in the textbook of
Diggle (2003); see pages 1, 14, 19, 22, 24, 56--57 and 61.
}
