mk_rx_obj: Makes an rxode2 Object

In ruminate: A Pharmacometrics Data Transformation and Analysis Tool

Makes an rxode2 Object

Description

Creates an rxode2 object from a model (either rxode2 function or a NONMEM file)

Usage

mk_rx_obj(type, model)

Arguments

type	Type of supplied model can be "rxode2", "NONMEM"
model	List containing the relevant information about the model. This will depend on the model types. rxode2: The supplied model is in the rxode2 format. fcn_def: Character string containing function definition. fcn_obj: Name of the funciton object created in fcn_def. NONMEM: The supplied model is in NONMEM format (either a control model_file: Character string containing the NONMEM model file.

Value

Results of FM_tc() when running the model. This will include a field isgood which is a boolean variable indicating success or failure. See the documentation for FM_tc() for the format returned when evaluation results in a failure and how to address those. When successful the capture field will contain the following:

• fcn_obj: The function name.

• rx_obj: The built rxode2 object.

Examples

fcn_def = ' my_func = function ()
   {
       description <- "One compartment PK model with linear clearance"
       ini({
           lka <- 0.45
           label("Absorption rate (Ka)")
           lcl <- 1
           label("Clearance (CL)")
           lvc <- 3.45
           label("Central volume of distribution (V)")
           propSd <- c(0, 0.5)
           label("Proportional residual error (fraction)")
       })
       model({
           ka <- exp(lka)
           cl <- exp(lcl)
           vc <- exp(lvc)
           cp <- linCmt()
           cp ~ prop(propSd)
       })

   }'
fcn_obj = "my_func"
model = list(fcn_def = fcn_def,
             fcn_obj = fcn_obj)

# function object

# rxode2 object
