Report one patch or one turtle among agents which has its variable equals to the maximum value.

# S4 method for matrix,worldMatrix,missing
maxOneOf(agents, world)

# S4 method for matrix,worldArray,character
maxOneOf(agents, world, var)

# S4 method for agentMatrix,missing,character
maxOneOf(agents, var)

Arguments

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`.

world

WorldMatrix or worldArray object.

var

Character. The name of the selected agents variable. If agents are patches and the world is a worldMatrix object, var must not be provided. If agents are patches and the world is a worldArray object, var is the name of the layer to use to define the patches values. If agents are turtles, var is one of the turtles' variable and can be equal to xcor, ycor, any of the variables created when turtles were created, as well as any variable created using turtlesOwn().

Value

Matrix (ncol = 2, nrow = 1) with the first column pxcor and the second column pycor representing the coordinates of the patch

(or of one of the patches) among the agents which has its variable equals to the maximum value among the agents, or

    `AgentMatrix` of length 1 representing the `turtle` (or one of

    the `turtles`) among the `agents` which has its variable `var`

    equals to the maximum value

    among the `agents`.

Details

world must not be provided if agents are turtles.

     If there are several `patches` or `turtles` among `agents` with their

     variable equal to the maximum

     value, one is chosen randomly. To access to all `patches` or `turtles` among

     `agents` which have their variable equal

     to the maximum value, use `withMax()`.

Examples

# Patches
w1 <- createWorld(
  minPxcor = 0, maxPxcor = 4, minPycor = 0, maxPycor = 4,
  data = sample(1:5, size = 25, replace = TRUE)
)
plot(w1)

p1 <- maxOneOf(agents = patches(w1), world = w1)

# Turtles
t1 <- createTurtles(
  n = 10, coords = randomXYcor(w1, n = 10),
  heading = sample(1:3, size = 10, replace = TRUE)
)
t2 <- maxOneOf(agents = t1, var = "heading")
