This function simulates planning units for RAP.

sim.pus(
  n,
  xmn = -sqrt(n)/2,
  xmx = sqrt(n)/2,
  ymn = -sqrt(n)/2,
  ymx = sqrt(n)/2
)

Arguments

n

integer number of planning units. sqrt(n) must yield a valid number.

xmn

numeric value for minimum x-coordinate.

xmx

numeric value for maximum x-coordinate.

ymn

numeric value for minimum y-coordinate.

ymx

numeric value for maximum y-coordinate.

Value

sp::SpatialPolygons() with planning units.

Details

Square planning units are generated in the shape of a square. Default coordinate arguments are such that the planning units will be centered at origin. The data slot contains an "id" (integer), "cost" (numeric), "status" (integer), and "area" (numeric).

Examples

# generate 225 sqauare planning units arranged in a square # with 1 unit height / width x <- sim.pus(225) # generate 225 rectangular pus arranged in a square y <- sim.pus(225, xmn = -5, xmx = 10, ymn = -5, ymx = 5) # \dontrun{ par(mfrow = c(1, 2)) plot(x, main = "x") plot(y, main = "y")
par(mfrow = c(1, 1)) # }
