Wrapper for stats::optim that returns the g3_cpp parameter template with optimised values

Description

Wrapper for stats::optim that returns the g3_cpp parameter template with optimised values

Usage

g3_optim(
  model,
  params,
  use_parscale = TRUE,
  method = "BFGS",
  control = list(),
  print_status = FALSE,
  print_id = "g3_optim",
  check_finite = TRUE,
  ...
)

Arguments

`model`	Either a g3 model of class 'g3_cpp', i.e., model <- gadget3::g3_to_tmb(actions), or an objective function from gadget3::g3_tmb_adfun(model, param)
`params`	The parameter template for a g3_cpp classed model.
`use_parscale`	Should parscale be used g3_tmb_parscale(params), see `optim`
`method`	The optimisation method, see `optim`
`control`	List of control options for optim, see `optim`
`print_status`	Print step comments, does not suppress comments from optim call (see control$trace)
`print_id`	A character string appended to the print statements (useful for when running g3_optim in parallel)
`check_finite`	boolean Should we check that initial/final conditions produce finite results before running?
`...`	Further arguments to be passed gadget3::g3_tmb_adfun, see `g3_tmb_adfun`
