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)
