[R] Simple cat statement - output truncated

[Stavros Macrakis]

Kevin,

The habitués of this mailing list get irritated when users mail in
problem reports which don't include enough information to reproduce
the problem, as requested in the standard footer of r-help mail
("PLEASE ... provide commented, minimal, self-contained, reproducible
code.") This irritation is sometimes expressed aggressively and
sometimes humorously. Be thankful that you drew "humorously".

So... please provide minimal, self-contained code that allows us to
reproduce your problem.  What is meant by "self-contained"?  It is
code that if you type it in to a fresh R, elicits your problem.  This
includes setting any necessary variables to appropriate values etc.

            -s

It is just a theory but say that the components array is not dimmensioned for 4 elements. It seems a little strange if that is the case that a reference error is not thrown and just the output of the cat call is affected.
