WorldMatrix or worldArray object.


Matrix (ncol = 2) with the first column pxcor and the second column pycor representing the patches coordinates, or

AgentMatrix object representing the moving agents.


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().


Vector of values for the agents if one variable is requested. The class depends of the variable class. The order of the vector follows the order of the agents, or

Matrix or Dataframe (ncol = length(var), nrow = NLcount(agents)) if more than one variable is requested. The row order follows the order of the agents.


world must be provided only if agents are patches.
