In OasisR: Outright Tool for the Analysis of Spatial Inequalities and Segregation

A function to compute the spatial units' perimeters

Description

The function is based on on sf and lwgeom packages and can be used with a shape file or an R spatial object (class sf, sfc or sfg).

Usage

perimeter(spatobj = NULL, folder = NULL, shape = NULL)

Arguments

spatobj	- a spatial object (class sf, sfc or sfg) containing geographic information
folder	- a character vector with the folder (directory) name indicating where the shapefile with the geographic information is located.
shape	- a character vector with the name of the shapefile (without the .shp extension) which contains the geographic information

Value

A perimeter vector
