are suppose to be passed to optim, according to the documentation. This
means you can't get the hessian to be returned, for example (so this is
a real problem, and not just a question of mistaken documentation).
Hi, this is a minor problem in solve.default but I didn't see anyone
mention it. The function does not give "correct" error-handling if given
