How can I get repository instance?

I am quite new in Laravel repository.

I am using l5-repository package.

When I created resource controller, it created as following:

    public function __construct(MyRepository $repository, MyValidator $validator)
    {
        $this->repository = $repository;
        $this->validator  = $validator;
    }

I could get MyRepository instance with $this->repository in this controller.

But I need to use another repository in this controller.

I tried to get like this but failed.

$anotherRepo = new AnotherRepo(); // I think AnotherRepo` is interface.

I was going to get $anotherRepo->all() data but couldn't get $anotherRepo instance.

Please help me how can I get repository instance.
