Import a shapefile

Imports a shapefile, converting it to an object of class 'metapopulation' or 'landscape'.

Usage

import.shape(filename, path, species.col, ID.col, area.col, dispersal, 
class.landscape=FALSE)

Arguments

filename: Character vector with the shapefile name.
path: Character vector with the path to the file.
species.col: Character vector with the name of the column (in the shapefile) with the species occupancy data.
ID.col: Character vector with the name of the column (in the shapefile) with the patch Id.
area.col: Character vector with the name of the column (in the shapefile) with the patch area, in hectares.
dispersal: Species mean dispersal ability, in meters.
class.landscape: Should the output belong to the class 'metapopulation' or 'landscape'.

Value

Delivers an object of class 'metapopulation' or 'landscape'.

Note

The shapefile must be in project coordinates (units=meters and hectares).

Examples


if (FALSE) { # \dontrun{

rl1 <- import.shape(filename = "yourshapefile.shp"
      ,path = "C:/yourpath..."
      ,species.col= "column with species"
      ,ID.col="column with patch Id"
      ,area.col="Column with area"
      ,dispersal=800#Mean dispersal ability of the species 
      #(used to generate patch clusters, or components)
      )

} # }
