That would make sense, I've tried to propose they add it as a feature in 
the rstudioapi.  However, since the noRstudioGD option now exists in R, 
I'd think it should behave consistently across platforms?  Opening pdf 
on one and interactive on another seems odd.

Great idea, I'll employ this workaround for now. Thanks!
