parseName: Parse model coding vector to model name

Description

Converts an ordinal model-coding vector into a single pharmacokinetic model name string, using a search space configuration.

Usage

parseName(modcode, search.space = NULL, custom_config = NULL)

Value

A character string representing the constructed model name.

Arguments

modcode

Numeric vector of model-coding flags/values in the order defined by the search space configuration.

search.space

Character string specifying which search space to use. Options are "ivbase", "oralbase", or "custom". Default is "ivbase".

custom_config

Optional named list defining a custom parameter structure. If provided, the parameter names are taken from the names of this list. If NULL, a default parameter structure is used based on the selected search space.

Details

The function selects a configuration (either a custom configuration when search.space is "custom", or the predefined configuration from spaceConfig(search.space) otherwise). It then decodes modcode with parseParams() and assembles an underscore-separated model name.

The name is built from these blocks in order: prefix, compartments, optional absorption, ETA block, elimination, correlation, residual error, and optional allometric scaling.

Key rules:

• The prefix is taken from config$prefix when available; otherwise from config$route; otherwise from search.space.

• The absorption block is included when any absorption option is present. If abs.type, abs.delay, and abs.bio are all missing/NA, the absorption block is included only for oral or mixed routes using FO_abs; otherwise it is omitted.

• The ETA block includes all eta.* terms equal to 1 (NA values are ignored), and also forces Vmax when mm equals 1; otherwise it forces CL.

• Elimination uses FO_elim when mm is 0 or NA, and MM_elim when mm is 1. Correlation uses uncorrelated when mcorr is 0 or NA, and correlated when mcorr is 1. Residual error uses add, prop, or combined.

• Allometric scaling is omitted when allometric_scaling is 0 or NA; otherwise it appends "asWT", "asBMI", or "asFFM".

# Example 1: Parse IV base model name
parseName(c(1, 0, 0, 0, 0, 0, 0, 0, 0, 1), "ivbase")

# Example 2: Parse oral base model name
parseName(c(2, 1, 1, 0, 0, 1, 1, 1, 0, 1, 3), "oralbase")

# Example 3: Parse custom configuration model name
custom_config <- list(
  prefix = "custom",
  route  = "oral",
  params = c("no.cmpt", "eta.cl", "eta.vc", "mm", "mcorr", "rv"),
  param_dependencies = list(),
  fixed_params = list()
)
parseName(c(2, 1, 0, 0, 1, 2), search.space = "custom",
custom_config = custom_config)
