minOneOf: One 'agent' with minimum

In NetLogoR: Build and Run Spatially Explicit Agent-Based Models

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 signature 'matrix,worldMatrix,missing'
minOneOf(agents, world)

## S4 method for signature 'matrix,worldArray,character'
minOneOf(agents, world, var)

## S4 method for signature 'agentMatrix,missing,character'
minOneOf(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().

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()`.

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`.

Examples

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