Set the `turtles`

' `heading`

towards `agents2`

.

```
face(turtles, agents2, world, torus = FALSE)
# S4 method for agentMatrix,matrix
face(turtles, agents2, world, torus = FALSE)
```

- turtles
`AgentMatrix`

object representing the moving`agents`

.- agents2
Matrix (

`ncol`

= 2) with the first column`pxcor`

and the second column`pycor`

representing the`patches`

coordinates, or`AgentMatrix`

object representing the moving`agents`

, orMatrix (

`ncol`

= 2) with the first column`x`

and the second column`y`

representing locations coordinates.- world
`WorldMatrix`

or`worldArray`

object.- torus
Logical to determine if the

`world`

is wrapped. Default is`torus = FALSE`

.

`AgentMatrix`

representing the `turtles`

with updated `headings`

.

The number of agents/locations in `agents2`

must be equal to 1 or
to the length of `turtles`

.

If `torus = FALSE`

, `world`

does not need to be provided.

If `torus = TRUE`

and the distance from one `turtles`

to
its corresponding agent/location `agents2`

is smaller around the
sides of the `world`

than across it, then the direction to the agent/location
`agents2`

going around the sides of the `world`

is given to the `turtle`

.

If a turtle is facing its own location, its heading does not change.
