That message means that R thinks it is being run non-interactively, 
which sounds appropriate in your case.  Choose one of the options.

You'll also inappropriately get the message when running R in some 
shells that don't look like consoles to R.  Then the right solution is 
to use --ess (which tells R that despite what it sees, it really is 
being run interactively.)

That's because you're using an obsolete version of R, that doesn't 
support the integer constant 29L.
