A function to compute the distance from spatial units centroids to the center

Description

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

Usage

distcenter(spatobj = NULL, folder = NULL, shape = NULL, 
center = 1, distin = 'm',  distout = 'm')

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
center	the row number of the center
distin	input metric conversion, based on measurements package and includes conversions from 'm', 'km', 'inch', 'ft', 'yd', 'mi', 'naut_mi', etc.
distout	output metric conversion, based on measurements package and includes conversions to 'm', 'km', 'inch', 'ft', 'yd', 'mi', 'naut_mi', etc.

Value

A vector with the distance to the center's centroid

Examples

distcenter(segdata, center = 46) 
foldername <- system.file('extdata', package = 'OasisR')
shapename <- 'segdata'
distcenter(folder = foldername, shape = shapename, center = 19)
