Package 'babelmixr2' reference manual

Title:	Use 'nlmixr2' to Interact with Open Source and Commercial Software
Description:	Run other estimation and simulation software via the 'nlmixr2' (Fidler et al (2019) <doi:10.1002/psp4.12445>) interface including 'PKNCA', 'NONMEM' and 'Monolix'. While not required, you can get/install the 'lixoftConnectors' package in the 'Monolix' installation, as described at the following url <https://monolixsuite.slp-software.com/r-functions/2024R1/installation-and-initialization>. When 'lixoftConnectors' is available, 'Monolix' can be run directly instead of setting up command line usage.

Expand a babelmixr2 PopED database

Description

Expand a babelmixr2 PopED database

Usage

babel.poped.database(popedInput, ..., optTime = NA)
babel.poped.database(popedInput, ..., optTime = NA)

Arguments

`popedInput`	The babelmixr2 generated PopED database
`...`	other parameters sent to `PopED::create.poped.database()`
`optTime`	boolean to indicate if the global time indexer inside of babelmixr2 is reset if the times are different. By default this is `TRUE`. If `FALSE` you can get slightly better run times and possibly slightly different results. When `optTime` is `FALSE` the global indexer is reset every time the PopED rxode2 is setup for a problem or when a poped dataset is created. You can manually reset with `popedMultipleEndpointResetTimeIndex()`

Value

babelmixr2 PopED database (with $babelmixr2 in database)

)

bblDatToPknca(
  model,
  data,
  table = nlmixr2est::tableControl(),
  rxControl = rxode2::rxControl(),
  env = NULL
)

Arguments

`model`	rxode2 model for conversion
`data`	Input dataset.
`table`	is the table control; this is mostly to figure out if there are additional columns to keep.
`rxControl`	is the rxode2 control options; This is to figure out how to handle the addl dosing information.
`env`	When `NULL` (default) nothing is done. When an environment, the function `nlmixr2est::.foceiPreProcessData(data, env, model, rxControl)` is called on the provided environment.

Value

With the function bblDatToMonolix() return a list with:

Monolix compatible dataset ($monolix)
Monolix ADM information ($adm)

With the function nlmixrDataToNonmem() return a dataset that is compatible with NONMEM.

With the function nlmixrDataToMrgsolve() return a dataset that is compatible with mrgsolve. Unlike NONMEM, it supports replacement events with evid=8 (note with rxode2 replacement evid is 5).

With the function nlmixrDataToRxode() this will normalize the dataset to use newer evid definitions that are closer to NONMEM instead of any classic definitions that are used at a lower level

  ...
)

Arguments

`nbSSDoses`	Number of steady state doses (default 7)
`useLinearization`	Use linearization for log likelihood and fim.
`stiff`	boolean for using the stiff ODE solver
`addProp`	specifies the type of additive plus proportional errors, the one where standard deviations add (combined1) or the type where the variances add (combined2). The combined1 error type can be described by the following equation: $y = f + (a + b\times f^c) \times \varepsilon$ The combined2 error model can be described by the following equation: $y = f + \sqrt{a^2 + b^2\times f^{2\times c}} \times \varepsilon$ Where: - y represents the observed value - f represents the predicted value - a is the additive standard deviation - b is the proportional/power standard deviation - c is the power exponent (in the proportional case c=1)
`exploratoryAutoStop`	logical to turn on or off exploratory phase auto-stop of SAEM (default 250)
`smoothingAutoStop`	Boolean indicating if the smoothing should automatically stop (default `FALSE`)
`burnInIterations`	Number of burn in iterations
`smoothingIterations`	Number of smoothing iterations
`exploratoryIterations`	Number of iterations for exploratory phase (default 250)
`simulatedAnnealingIterations`	Number of simulating annealing iterations
`exploratoryInterval`	Minimum number of iterations in the exploratory phase (default 200)
`exploratoryAlpha`	Convergence memory in the exploratory phase (only used when `exploratoryAutoStop` is `TRUE`)
`omegaTau`	Proportional rate on variance for simulated annealing
`errorModelTau`	Proportional rate on error model for simulated annealing
`variability`	This describes the methodology for parameters without variability. It could be: - Fixed throughout (none) - Variability in the first stage (firstStage) - Decreasing until it reaches the fixed value (decreasing)
`runCommand`	is a shell command or function to run monolix; You can specify the default by `options("babelmixr2.monolix"="runMonolix")`. If it is empty and 'lixoftConnectors' is available, use lixoftConnectors to run monolix. See details for function usage.
`rxControl`	'rxode2' ODE solving options during fitting, created with 'rxControl()'
`sumProd`	Is a boolean indicating if the model should change multiplication to high precision multiplication and sums to high precision sums using the PreciseSums package. By default this is `FALSE`.
`optExpression`	Optimize the rxode2 expression to speed up calculation. By default this is turned on.
`calcTables`	This boolean is to determine if the foceiFit will calculate tables. By default this is `TRUE`
`compress`	Should the object have compressed items
`ci`	Confidence level for some tables. By default this is 0.95 or 95% confidence.
`sigdigTable`	Significant digits in the final output table. If not specified, then it matches the significant digits in the 'sigdig' optimization algorithm. If 'sigdig' is NULL, use 3.
`absolutePath`	Boolean indicating if the absolute path should be used for the monolix runs
`modelName`	Model name used to generate the NONMEM output. If `NULL` try to infer from the model name (could be `x` if not clear). Otherwise use this character for outputs.
`muRefCovAlg`	This controls if algebraic expressions that can be mu-referenced are treated as mu-referenced covariates by: 1. Creating a internal data-variable 'nlmixrMuDerCov#' for each algebraic mu-referenced expression 2. Change the algebraic expression to 'nlmixrMuDerCov# * mu_cov_theta' 3. Use the internal mu-referenced covariate for saem 4. After optimization is completed, replace 'model()' with old 'model()' expression 5. Remove 'nlmixrMuDerCov#' from nlmix2 output In general, these covariates should be more accurate since it changes the system to a linear compartment model. Therefore, by default this is 'TRUE'.
`run`	Should monolix be run and the results be imported to nlmixr2? (Default is TRUE)
`...`	Ignored parameters

Details

If runCommand is given as a string, it will be called with the system() command like:

runCommand mlxtran.

For example, if runCommand="'/path/to/monolix/mlxbsub2021' -p " then the command line used would look like the following:

'/path/to/monolix/mlxbsub2021' monolix.mlxtran

If runCommand is given as a function, it will be called as FUN(mlxtran, directory, ui) to run Monolix. This allows you to run Monolix in any way that you may need, as long as you can write it in R. babelmixr2 will wait for the function to return before proceeding.

If runCommand is NA, nlmixr() will stop after writing the model files and without starting Monolix.

Note that you can get the translated monolix components from a parsed/compiled rxode2 ui object with ui$monolixModel and ui$mlxtran

Value

A monolix control object

Estimate starting parameters using PKNCA

Description

Estimate starting parameters using PKNCA

Usage

## S3 method for class 'pknca'
nlmixr2Est(env, ...)
## S3 method for class 'pknca'
nlmixr2Est(env, ...)

Arguments

env

Environment for the nlmixr2 estimation routines.

This needs to have:

- rxode2 ui object in '$ui'

- data to fit in the estimation routine in '$data'

- control for the estimation routine's control options in '$ui'

...

Other arguments provided to 'nlmixr2Est()' provided for flexibility but not currently used inside nlmixr

Details

Parameters are estimated as follows:

ka 4 half-lives to Tmax but not higher than 3: log(2)/(tmax/4)
vc Inverse of dose-normalized Cmax
cl Estimated as the median clearance
vp,vp22- and 4-fold the vc, respectively by default, controlled by the vpMult and vp2Mult arguments to pkncaControl
q,q2 0.5- and 0.25-fold the cl, respectively by default, controlled by the qMult and q2Mult arguments to pkncaControl

The bounds for the parameter estimates are set to 10% of the first percentile and 10 times the 99th percentile. (For ka, the lower bound is set to the lower of 10% of the first percentile or 0.03 and the upper bound is not modified from 10 times the 99th percentile.)

Parameter estimation methods may be changed in a future version.

Value

A model with updated starting parameters. In the model a new element named "nca" will be available which includes the PKNCA results used for the calculation.

Get Multiple Endpoint Modeling Times

Description

This function takes a vector of times and a corresponding vector of IDs, groups the times by their IDs, initializes an internal C++ global TimeIndexer, that is used to efficiently lookup the final output from the rxode2 solve and then returns the sorted unique times.

The popedMultipleEndpointIndexDataFrame() function can be used to visualize the internal data structure inside R, but it does not show all the indexes in the case of time ties for a given ID. Rather it shows one of the indexs and the total number of indexes in the data.frame

Usage

popedGetMultipleEndpointModelingTimes(times, modelSwitch, sorted = FALSE)

popedMultipleEndpointIndexDataFrame(print = FALSE)
popedGetMultipleEndpointModelingTimes(times, modelSwitch, sorted = FALSE)

popedMultipleEndpointIndexDataFrame(print = FALSE)

Arguments

`times`	A numeric vector of times.
`modelSwitch`	An integer vector of model switch indicator corresponding to the times
`sorted`	A boolean indicating if the returned times should be sorted
`print`	boolean for `popedMultipleEndpointIndexDataFrame()` when `TRUE` show each id/index per time even though it may not reflect in the returned data.frame

Value

A numeric vector of unique times.

Examples





times <- c(1.1, 1.2, 1.3, 2.1, 2.2, 3.1)
modelSwitch <- c(1, 1, 1, 2, 2, 3)
sortedTimes <- popedGetMultipleEndpointModelingTimes(times, modelSwitch, TRUE)
print(sortedTimes)

# now show the output of the data frame representing the model
# switch to endpoint index

popedMultipleEndpointIndexDataFrame()

# now show a more complex example with overlaps etc.

times <- c(1.1, 1.2, 1.3, 0.5, 2.2, 1.1, 0.75,0.75)
modelSwitch <- c(1, 1, 1, 2, 2, 2, 3, 3)
sortedTimes <- popedGetMultipleEndpointModelingTimes(times, modelSwitch, TRUE)
print(sortedTimes)

popedMultipleEndpointIndexDataFrame(TRUE) # Print to show individual matching


times <- c(1.1, 1.2, 1.3, 2.1, 2.2, 3.1)
modelSwitch <- c(1, 1, 1, 2, 2, 3)
sortedTimes <- popedGetMultipleEndpointModelingTimes(times, modelSwitch, TRUE)
print(sortedTimes)

# now show the output of the data frame representing the model
# switch to endpoint index

popedMultipleEndpointIndexDataFrame()

# now show a more complex example with overlaps etc.

times <- c(1.1, 1.2, 1.3, 0.5, 2.2, 1.1, 0.75,0.75)
modelSwitch <- c(1, 1, 1, 2, 2, 2, 3, 3)
sortedTimes <- popedGetMultipleEndpointModelingTimes(times, modelSwitch, TRUE)
print(sortedTimes)
