Neighbors patches

Description

Report the coordinates of the neighbors patches around the agents.

Usage

neighbors(world, agents, nNeighbors, torus = FALSE)

## S4 method for signature 'worldNLR,matrix,numeric'
neighbors(world, agents, nNeighbors, torus = FALSE)

Arguments

world

WorldMatrix or worldArray object.

agents

Matrix (ncol = 2) with the first column pxcor and the second column pycor representing the patches coordinates, or

          `AgentMatrix` object representing the moving `agents`.
nNeighbors

Integer: 4 or 8. Represents the number of neighbor patches considered.

torus

Logical to determine if the world is wrapped. Default is torus = FALSE.

Details

The patch around which the neighbors are identified, or the patch where the turtle is located on around which the neighbors are identified, is not returned.

     If `torus = FALSE`, `agents` located on the edges of the
     `world` have less than `nNeighbors` patches around them.
     If `torus = TRUE`, all `agents` located on the edges of the
     `world` have `nNeighbors` patches around them,
     which some may be on the other sides of the `world`.

Value

Matrix (ncol = 3) with the first column pxcor and the second column pycor representing the coordinates of the neighbors patches around the agents and the third column id representing the id of the agents in the order provided.

Examples

w1 <- createWorld(minPxcor = 0, maxPxcor = 9, minPycor = 0, maxPycor = 9)
if (requireNamespace("SpaDES.tools", quietly = TRUE)) {
  neighbors(world = w1, agents = patch(w1, c(0, 9), c(0, 7)), nNeighbors = 8)
  t1 <- createTurtles(n = 3, coords = randomXYcor(w1, n = 3))
  neighbors(world = w1, agents = t1, nNeighbors = 4)
}
