optimizeR 0.3.0

CRAN release: 2023-01-22

• Function set_optimizer() was renamed to define_optimizer().

• Inputs for define_optimizer() were renamed for clarity:

  • opt_fun -> optimizer

  • v -> value
  • z -> parameter
  • out_ign -> output_ignore
  • test_par -> validation_settings

• Elements for input validation_settings have been simplified, please see the documentation of define_optimizer().

• Elements in the output of apply_optimizer() were renamed for clarity:

  • v -> value
  • z -> parameter
