xgeo: A function to compute all spatial info for segregation indexes

Description

The function is based on rgdal, rgeos and spdep packages and it can be used by providing a shape file or a R spatial object (SpatialPolygonsDataFrame).

Usage

xgeo(spatobj = NULL, folder = NULL, shape = NULL, center = 1)

Arguments

spatobj

- a Spatial object (SpatialPolygonsDataFrame)

folder

- a character vector with the folder (directory) where the shapefile is

shape

- a character vector with the name of the shapefile (without the .shp extension)

center

- the row number of the center

Value

• A list that contains all geographic information needed to calculate segregation indexes.

shapename <- 'AnnHAge'
xgeo(folder = foldername, shape = shapename, center = 19)
