\title{Spatial pattern of Couepia caryophylloides in Paracou, a canopy tree species of French Guiana.}
\description{
Spatial pattern of 34 mature individuals and 173 young individuals of the tree species \emph{Couepia caryophylloides} (Chrysobalanaceae) in a 25-ha forest plot in Paracou, French Guiana.

\usage{data(Couepia)}
\format{
A list with 4 components:\cr
\code{$rect } is a vector of coordinates \eqn{(xmin,ymin,xmax,ymax)} of the origin and the opposite corner of a 500 by 500 m rectangular plot.\cr
\code{$tri } is a list of vertex coordinates \eqn{(ax,ay,bx,by,cx,cy)} of contiguous triangles covering swampy parts of the plot.\cr
\code{$trees } is a list of tree coordinates \eqn{(x,y)}.\cr
\code{$stage } is a factor with 2 levels \eqn{("mature","young")}.\cr
