Create a metamodel file from an NlmePmlModel — create_metamodel_from

Creates (or overwrites) a textual metamodel file (e.g. .mmdl) from a supplied NlmePmlModel object. This is the inverse of read_mmdl().

Usage

create_metamodel_from_model(
  model,
  metamodelFile,
  datafile,
  author = "",
  engineParams = NULL,
  tableParams = NULL,
  absolutePaths = FALSE
)

Arguments

model: An NlmePmlModel object.
metamodelFile: Output metamodel file path to create/overwrite.
datafile: Input data file path to write into the ## DATA block.
author: Optional author string to write into the metamodel.
engineParams: Optional NlmeEngineExtraParams object created by engineParams() to serialize into the ## ESTARGS block. Only arguments that differ from engineParams() defaults for this model (and estimation method) are written.
tableParams: Optional table definition(s) created by tableParams() (i.e., NlmeTableDef and/or NlmeSimTableDef, or a list of them) to serialize into the ## TABLES block.
absolutePaths: Logical; controls how datafile is written into the ## DATA block. FALSE (default) writes a path relative to the metamodel directory (e.g. ./data.csv), keeping the resulting metamodel portable across machines. TRUE writes a normalized absolute path, useful when the dataset lives outside the metamodel tree (shared drive, central data location). When relative resolution is not possible (e.g. different Windows drive), the function warns and falls back to an absolute path.

Value

Invisible model.

Examples

if (FALSE) { # \dontrun{
tmp_data <- tempfile(fileext = ".csv")
write.csv(Certara.RsNLME::pkData, tmp_data, row.names = FALSE)

m <- Certara.RsNLME::pkmodel(data = Certara.RsNLME::pkData, workingDir = tempdir())
ep <- Certara.RsNLME::engineParams(m, method = "FOCE-ELS", numIterations = 200)

out_mmdl <- file.path(tempdir(), "example.mmdl")
Certara.RsNLME::create_metamodel_from_model(m, out_mmdl, datafile = tmp_data, engineParams = ep)
} # }
