Update model ID (run number) in the control stream

Helper to update the model ID (aka the "run number" if models are named numerically) in the new control stream of a model created with copy_model_from(). See Details section.

Usage

update_model_id(
  .mod,
  .suffixes = c(".msf", ".ext", ".tab", ".chn", "par.tab"),
  .additional_suffixes = NULL
)

Arguments

.mod

The bbi_nonmem_model object associated with the control stream that will be modified.

.suffixes

Character vector of suffixes to be matched for replacement. Matching is case insensitive (see Details). Note that if passed suffixes are file extensions, you must include the leading period (e.g. pass ".tab" instead of "tab"). This is to enable passing things like "par.tab" which should (and will) match {parent_mod}par.tab but not {parent_mod}.par.tab.

.additional_suffixes

Character vector of suffices to match in addition to those passed in .suffixes. NULL by default. This is useful if you want to use the defaults for .suffixes, but also add new ones, as opposed to replacing the defaults. Also, see note in .suffixes about file extensions.

Value

Invisibly returns .mod, to enable piping (i.e. from copy_model_from())

Details

This function updates all occurrences of the model ID from the parent model and replaces them with model ID from the new model. Importantly, it relies on the assumption that .mod will have the parent model ID as the first entry in .mod$based_on. This will be true if .mod was created by copy_model_from().

It will look for that parent model ID before all strings passed to .suffixes or .additional_suffixes (e.g. {parent_mod}.MSF, etc.) replace it with get_model_id(.mod) wherever found.

.suffixes defaults to the following:

• .msf

• .ext

• .chn

• .tab

• par.tab

All matches are not case sensitive but replacements are. For example, if .msf is passed as a suffix, {parent_mod}.MSF and {parent_mod}.msf would both be replaced, but the case of the suffix in the control stream will be maintained as is.
