Assign values to the agents for the selected variables.

NLset(world, turtles, agents, var, val)

# S4 method for missing,agentMatrix,agentMatrix,character
NLset(turtles, agents,
  var, val)

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

# S4 method for worldArray,missing,matrix,character
NLset(world, agents, var, val)

Arguments

world

WorldMatrix or worldArray object.

turtles

AgentMatrix object representing the moving agents.

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.

var

Character. Vector of the names of the selected agents variables. 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 layers to use to define the patches values. If agents are turtles, var is some of the turtles' variable and can be any of the variables created when turtles were created, as well as any variable created with turtlesOwn().

val

Numeric or character. Vector of length 1 or length NLcount(agents) if length(var) == 1, or

Matrix or Dataframe (ncol = length(var), nrow = NLcount(agents)). Columns must be in the same order as var.

Value

WorldMatrix or worldArray object with the values val assigned to the patches variables var for the agents, or

AgentMatrix representing the turtles with the values val assigned to the variables var for the agents.

Details

If agents are patches, world must be provided and turtles must not be provided. If agents are turtles, turtles must be provided and world must not be provided.
