Thank you for your answer. I assume, you suggest to use
capture.output(print(...)). Without your response I would have believed
that I had missed an important possibility of R.

Regarding the Cox-Model Ales Ziberna gave me a useful hint to use summary()
which returns a list.

Thanks to both of you,
