In r4ss/r4ss: R Code for Stock Synthesis

Read admodel.hes file

Description

This function reads in all of the information contained in the .hes file. Some is needed for relaxing the covariance matrix, while the rest is recorded and rewritten to file as ADMB expects.

Usage

getADMBHessian(
  hesfile = "admodel.hes",
  File = lifecycle::deprecated(),
  FileName = lifecycle::deprecated()
)

Arguments

hesfile	Name of .hes file, including the full path (can be relative to working directory).
File	Deprecated. Add path to hesfile input instead.
FileName	Deprecated. Use 'hesfile“ instead.

Value

A list with elements num.pars, hes, hybrid_bounded_flag, and scale.
