How to integrate R unit test with python unit test (nosetests)

I have developed unit test for python using nosetests. I have to write unit test for R code now which I want to integrate with my python unit test. Currently I am displaying in output the unit test failed and succeeded in python. I want to combine the output of R unit test with the python unit test. Is there a way that I can invoke R unit test using python and combine the outputs of python and R unittest.
