set_calibarea: Create minimum convex polygon based on species occurence data

In HemingNM/ENMwizard: Advanced Techniques for Ecological Niche Modeling Made Easy

Create minimum convex polygon based on species occurence data

Description

This function will create minimum convex polygon based on coordinates of species occurence data.

Usage

set_calibarea(
  occ.spdf,
  sp.nm = "species",
  convex = TRUE,
  alpha = 10,
  save = TRUE,
  crs.set = "+proj=longlat +datum=WGS84"
)

Arguments

occ.spdf	An object of class SpatialPoints or SpatialPointsDataFrame (e.g. species occurence coordinates)
sp.nm	Species name, used on saving shapefile
convex	Logical. Convex (T) or concave (F) polygon
alpha	Value of \alpha.
save	Should save polygons on disk?
crs.set	set the coordinate reference system (CRS) of the polygons

Value

An object of class SpatialPolygons or SpatialPolygonsDataFrame. Polygon built using coordinates of species occurence data

## Not run: 
occ.poly <- set_calibarea(occ.spdf, sp.nm="occ.poly")
plot(occ.poly)

## End(Not run)
