I'm sorry but that's far beyond my expertise. I am sure there is and it does not "look" all that hard to read from a db but I tend to use small data sets or existing ones that don't usually have input problems like that .
I am using a bog-standard labtop with 4GB RAM with Ubuntu 12.10 and R2.15.2 so if there is a limit I would have thought I'd experience it.
So I'm out of ideas though for RStudio it might be worth asking it on their website and see if they have any suggestions about limits or if it is a peculiarity of your setup.
Here's my sessionInfo for comparison.
