neighborGrowing: Growing of neighbors

In ggRaver/Lslide: Functions for object-oriented image analysis in landslide science

Growing of neighbors

Description

This function grows neighbor SpatialPolygonsDataFrame objects together

Usage

neighborGrowing(spdf, nb, ID.start = NULL, ID.class = NULL,
  return.input = TRUE, return.gUnaryUnionNeighbors = TRUE,
  quiet = TRUE)

Arguments

spdf	SpatialPolygonsDataFrame, or full path of a shapefile
nb	object neighborhood based on poly2nb
ID.start	vector containing ID's where the growing starts. Default: NULL
ID.class	ID's of a specific class in order to allow growing only for class members. Default: NULL
return.input	spdf is returned with neighbor information. Default: TRUE
return.gUnaryUnionNeighbors	return united neighbors based on gUnaryUnion. Default: TRUE
quiet	no outputs in console. Default: TRUE

Value

list containing input SpatialPolygonsDataFrame with information on growing neighbors, geometry with united neighbors, or both (default)

Note

• SpatialPolygonsDataFrame input must have an ID field with unique numbers
