Agents with minimum

Report the patches or turtles among agents which have their variable equals to the minimum value.

withMin(agents, world, var)

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

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

# S4 method for agentMatrix,missing,character
withMin(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) with the first column pxcor and the second column pycor representing the coordinates of the patches among the agents

which have their variable equal to the minimum value among the agents, or

    `AgentMatrix` representing the `turtles` among the `agents`

    which have their variable

    `var` equal to the minimum value among the `agents`.

Details

world must not be provided if agents are turtles.

Examples

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

p1 <- withMin(agents = patches(w1), world = w1)
#> Error in h(simpleError(msg, call)): error in evaluating the argument 'agents' in selecting a method for function 'withMin': unable to find an inherited method for function 'patches' for signature '"worldMatrix"'

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