check for libraries about habitatconnectivity HOT 3 CLOSED

from habitatconnectivity.

I found the following packages listed with a # are not used during the code at all. Raster, igraph, rworldmap, geosphere, colorspace and viridis are essential for this code. We can consider removing the libraries that are not essential (#).

library(raster)
#library(rgdal)
#library(expm)
library(igraph)
#library(maptools)
#library(rrcov)
#library(splines)
library(rworldmap)
#library(mapdata)
#library(sp)
#library(maps)
#library(rgeos)
library(geosphere)
#library(RColorBrewer)
data("countriesLow")
library("colorspace")
library(viridis)
