# R through Sage giving errors: Error: object 'sage3' not found

I am trying to use R through Sage and I have read about how the interface works so I think I am entering in the right code. I have tried this on two different computers and get the same errors. One is an quad core 64 bit Ubuntu 10 guest on VMWare Workstation 7 with host Win 7 the other is a single core 32bit Ubuntu 12 pure Linux install when I access R methods I get errors of the form:

Error: object 'sageX' not found where X is a number between 0 and 3

examples:

r.read_csv(DATA+'transaction_data.csv',header=True)

Error: object 'sage2' not found

and

r.read_table(header=True, text = "a b 1 2 3 4") Error: object 'sage3' not found

I did find a trac that seems to be related to the error I'm getting: http://trac.sagemath.org/sage_trac/ticket/839 But this is from 4 years ago, this issue must have been taken care of by now right? I'm using Sage 4.8

Let me know if you have any idea how to fix this or if there might be something I did wrong during the installation
