Return error messages from R?

[NielsKSchjoedt]

Is it possible to get the "real" error message from R? No matter what kind of error that occurs, I get the same exception from Rserve. Here is an example:

con.eval('summary(some_undefined_object)')
#=> Rserve::Connection::EvalError: eval failed: Packet[cmd=2130771970,len=<nil>, con='<nil>', status=error:'Unknown variable/method'(127)]

Where the actual error message when evaluated in R is:

> summary(some_unknown_var)
Error in summary(some_unknown_var) : object 'some_unknown_var' not found

I would also love to see the actual error message attached to the Rserve response.
