param_tags: Return parameter tags

In mrgsolve: Simulate from ODE-Based Models

Return parameter tags

Description

Use this function if you added the ⁠@covariates⁠ or ⁠@input⁠ attributes or specified a user-defined tag (via ⁠@tag⁠) in one or more parameter blocks and need to extract that information. Also, using the ⁠$INPUT⁠ block to declare parameters will automatically add the input tag (via ⁠@input⁠). Once these attributes / tags are added, you can use check_data_names() to reconcile names of input data sets against tagged model parameters.

Usage

param_tags(x)

Arguments

x	mrgsolve model object.

Value

A data frame listing parameter names and their tags.

Model specification

Note: it is good practice to tag parameters where appropriate with input or covariates as these will automatically be expected on input data when you call check_data_names(). User-defined tags are also possible, but you will need to alert check_data_names() to look for them.

Model Specification Examples

You can use the ⁠$INPUT⁠ block to add the input tag on these parameters

$INPUT 
STUDY = 101, WT = 70, DVID = 1

Tag some covariates in the model

$PARAM @covariates
WT = 70, SEX = 1, EGFR = 110

A user-defined tag

$PARAM @tag flags
FFLAG = 1, DFLAG = 0
