[R] sem package, suppress warnings

[John Fox]

Dear Dustin and Steve,

For some reason, I didn't see Dustin's original message.

As documented in ?sem, the warn argument to sem() covers only warnings
directly produced by the optimizer,

	"warn: if TRUE, warnings produced by the optimization function will
be printed. This should generally not be necessary, since sem prints its own
warning, and saves information about convergence. The default is FALSE."

It doesn't cover the warnings produced by sem() itself. For that, you can do
as Steve suggests, or simply set options(warn = -1). The debug argument is
FALSE by default and if TRUE prints the iteration history and some
additional information; it is irrelevant to warnings.

I hope this helps,
 John
