Standardize and simplify data for nlmixr2 estimation

Description

This function is typically not needed by end users.

Usage

nlmixrDataSimplify(data, object, table = list(), est = NULL, control = NULL)

Arguments

data	nlmixr data
object	an nlmixr_ui object (e.g. the output of running nlmixr(object = model)
table	The output table control object (like 'tableControl()')
est	estimation method (all methods are shown by 'nlmixr2AllEst()'). Methods can be added for other tools
control	The estimation control object. These are expected to be different for each type of estimation method

Details

The standardization keeps columns that rxode2 and nlmixr2 use along with the covariates. Column order is standardized (rxode2 then nlmixr2 then alphabetically sorted covariates), and rxode2 and nlmixr2 column names are converted to lower case.

Some estimation methods take their covariates from the data instead of from the model; est="vae" searches the data for covariates to select. For those methods the covariate columns the search can pick from are kept as well, since dropping them would change the fit.

Value

The data with the nlmixr2 column lower case and on the left and the covariate columns on the right and alphabetically sorted.
