Creates a Region object

Description

This creates an instance of the Region class. If the user supplied a shapefile all information will be extracted from here. Otherwise the user needs to specify a list of polygons describing the areas of interest (coords) and optionally a list of polygons describing the areas to be excluded (gaps). If area is not specified it will be calculated.

Usage

make.region(region.name, strata.name = character(0), units,
  area = numeric(0), shapefile = NULL, coords = list(), gaps = list())

Arguments

Value

object of class Region

Examples

coords <- gaps <- list()
coords[[1]] <- list(data.frame(x = c(0,1000,1000,0,0), y = c(0,0,
 1000,1000,0)))
gaps[[1]] <- list(data.frame(x = c(400,600,500,350,400), y = c(100,
 250,600,120,100)))

region <- make.region(region.name = "study.area", units = "m", 
 coords = coords, gaps = gaps)
plot(region)
