tables with empty string cells can not be pushed to R #17

The node fails to push them. The problems occurs when it tries to assign a variable to the REXP that contains the table.

It's a problem with REngine: https://www.rforge.net/bugzilla/show_bug.cgi?id=194

If they don't fix it soon, we should revert to old version of REngine/RServe were this was working correctly.

We're currently using a workaround which converts empty strings to missing cells. This should do it until the Rserve people fix the bug.

The issue seems to be solved.
