Report the patches or the turtles among agents which have their variable
equals to specific values.

NLwith(agents, var, val)Matrix (ncol = 2) with the first column pxcor and the second
column pycor representing the patches coordinates, or
WorldMatrix or worldArray object.
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().
Numeric or character. Vector of any length.
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
equals to any val, or
world must not be provided if agents are turtles.
