Is there any way to suppress the extra white space from compiling in R?

edit

I've made some changes to slightly reduce whitespace in R mode for SageMathCloud (https://cloud.sagemath.com); restart your project to get this update. However, due to how Sage works they might not be sufficient. If you evaluate the following in a cell (in sage mode, or put %sage at the top), it will eliminate a lot of additional whitespace in %r mode.

def r_eval0(*args, **kwds):
    return sage.interfaces.r.R.eval(sage.interfaces.r.r, *args, **kwds).strip().replace('\n\n','')
sage_salvus.r_eval0 = r_eval0
