`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.
