Get or set a named-numeric vector of forced parameters stored in a hidden
slot of an rxode2 ui. Forced parameters override the values supplied in
params/data and the model initial estimates on every solve of that ui
(they are written into every subject/simulation column at solve setup, the
same injection point used by par-loader hooks). Because the values live on
the ui they travel with it – through model piping and into any nlmixr2 fit
built from it – so the model stays self-contained and portable (e.g. a fit
that carries trained neural-network weights re-solves, predicts and simulates
with those weights with no external state).
Details
The value is stored directly in the ui environment (not in the printed meta
block, so it stays hidden) and registered as a sticky model item so it
survives model piping. Names must be model parameters; names that are not
model parameters are ignored at solve time. Set to NULL (or an empty
vector) to clear.
