Hello.

Does anyone know what the error code "NEW_X" means in optim? Here is
what the return looks like:

	$counts
	function gradient
		 302      302

	$convergence
	[1] 1

	$message
	[1] "NEW_X"

I have searched and found a couple of mentions without responses:

Full disclosure, this is my (unanswered) question on R-devel


I can only find one instance of the call in `optim.c` and I don't
understand what it is doing.

Thank you,

Avraham Adler
