Hi,
I've been trying to use optim to minimise least squares for a
function, and then get a guess at the error using the hessian matrix
(calculated from numDeriv::hessian, which I read in some other r-help
post was meant to be more accurate than the hessian given in optim).

I've been trying to use optim to minimise least squares for a
function, and then get a guess at the error using the hessian matrix
(calculated from numDeriv::hessian, which I read in some other r-help
post was meant to be more accurate than the hessian given in optim).
