Report `TRUE`

if `agents`

is non empty, report `FALSE`

otherwise.

```
NLany(agents)
# S4 method for matrix
NLany(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`

.

Logical. `TRUE`

if there is at least one patch or one turtle in the
`agents`

, `FALSE`

otherwise.
