This is a wrapper around the rpy2.rinterface function with the

Args:
- env: an environment to use as a context. If not specified (None, the
default), a child environment to the current context is created.
- use_rlock: whether to use a threading lock (see the documentation about
"rlock". The default is True.
Returns:
Yield the environment (passed to env, or created).
