Load PBK model parameter values from a CSV

This function reads a CSV file of parameter values and returns a named numeric vector. Only rows matching the specified idInstance are used.

Usage

load_params(model, filename, param_instance, ...)

Arguments

model: An object of class sbmlModel for which the parametrisations should be loaded.
filename: Path to the CSV file containing parameters.
param_instance: The instance ID used to filter parameters. When not specified, it is assumed that the file contains only one parametrisation.
...: Additional arguments passed to read.csv.

Value

A named numeric vector with parameter values.

Details

The input CSV file must contain the following columns:

idModelInstance: A character string identifying the model instance. Used for filtering.
Parameter: The name of the parameter to be loaded. These will become the names of the output vector.
Value: The numeric value associated with each parameter.

Examples

model_file <- system.file("extdata/", "simple_oral.sbml", package = "sbmlpbk")
model <- load_sbml(model_file)
params_file <- system.file("extdata/", "simple_oral_params.csv", package = "sbmlpbk")
params <- load_params(model, params_file, 'simple_PARAM')
head(params)
