paracou: Kimboto trees at Paracou, French Guiana

Description

This dataset is a point pattern of adult and juvenile Kimboto trees (Pradosia cochlearia or P. ptychandra) recorded at Paracou in French Guiana. See Flores (2005).

The dataset paracou is a point pattern (object of class "ppp") containing the spatial coordinates of each tree, marked by age (a factor with levels adult and juvenile. The survey region is a rectangle approximately 400 by 525 metres. Coordinates are given in metres.
