[R] error handling in R/ lapack routines

[Spencer Graves]

	  I just did a Google search for "lapack error codes" and got several 
hits.  However, I don't know if a translation of "error code 17" would 
really help you.

	  Have you tried "fn" as a stand-alone function?  If yes, have you 
tried including a "cat" or "print" statement in it, so it prints the 
value (and maybe the arguments) before it actually returns it?  If optim 
is going to run more than a few seconds, I have "fn" print the value it 
returns.  If it returns NA. I see that, etc.

hope this helps.
