Kimboto trees at Paracou, French Guiana


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.

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.




Data kindly contributed by Olivier Flores. All data belong to CIRAD and UMR EcoFoG and are included in spatstat with permission. Original data sources: juvenile and some adult trees collected by Flores (2005); adult tree data sourced from CIRAD Paracou experimental plots dataset (2003 campaign).
