In adalardo/Rppsp: R functions to manage permanent plot data (short line)

Edge Data Correction

Description

Adjust border effect using a torus correction connecting vertical and horizontal borders for a continuous spaces

Usage

edgeData(
  x,
  y,
  xlim = c(0, 1),
  ylim = c(0, 1),
  rMax = min(c(xlim[2], ylim[2]))/4
)

Arguments

x, y	Numeric vectors with 'x' and 'y' coordinates in a cartesian space. They must have the same length.
xlim, ylim	Numeric vectors with two values defining the 'x' and 'y' axis limit in the cartesian plane.
rMax	Maximum distance for neighbors spatial statistics.

Value

'edgeData' returns a list with tree positions: 'edgeData' data with border torus correction coordinates ‘originalData' original data ’x' and 'y' coordinates ‘pointsVF' logical vector with the same length of ’edgeData' indicating the 'TRUE' data coordinates and 'FALSE' border adjustment coordinates.
