minOneOf: One agent with minimum

Description

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

Usage

minOneOf(agents, world, var)
# S4 method for matrix,worldMatrix,missing
minOneOf(agents, world)
# S4 method for matrix,worldArray,character
minOneOf(agents, world, var)
# S4 method for agentMatrix,missing,character
minOneOf(agents, var)

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 minimum 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 minimum value
    among the `agents`.

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().

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 minimum
     value, one is chosen randomly. To access to all `patches` or `turtles` among
     `agents` which have their variable equal
     to the minimum value, use `withMin()`.

# Patches

  minPxcor = 0, maxPxcor = 4, minPycor = 0, maxPycor = 4,
  data = sample(1:5, size = 25, replace = TRUE)
)

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

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