Preprocessing hook: mu-expand non-mu structural fixed-effect thetas for the nonparametric engines, before the rest of the pipeline builds on the ui. Doing it here (rather than mutating the ui mid-setup) keeps the injected pseudo-etas consistent through covariate/mu processing and model compilation. Off when control$muExpand is FALSE.

Usage

.nlmixr0preProcessNpMuExpand(ui, est, data, control)

Arguments

ui

rxode2 ui

est

estimation method (all methods are shown by `nlmixr2AllEst()`). Methods can be added for other tools

data

nlmixr data

control

The estimation control object. These are expected to be different for each type of estimation method

Value
