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

NLwith(agents, world, val)
# S4 method for matrix,worldArray,character
NLwith(agents, world, var, val)
# S4 method for agentMatrix,missing,character
NLwith(agents, var, val)
Matrix (ncol
= 2) with the first column pxcor
and the second
column pycor
representing the patches
coordinates, or
AgentMatrix
object representing the moving agents
.
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
AgentMatrix
representing the turtles
among the agents
which have their variable
var
equals to any val
.
world
must not be provided if agents
are turtles
.
This is equivalent in R to subsetting.
val
can include NA
.
