In nlmixr2est: Nonlinear Mixed Effects Models in Population PK/PD, Estimation Routines

Register / remove an estimation interceptor

Description

An interceptor is a 'function(env)' consulted in [nlmixr2Est()] before the standard estimation method is dispatched. It receives the fully set-up estimation environment ('env$ui', 'env$data', 'env$control', the est name in 'class(env)[1]', and any extra 'nlmixr2()' arguments in 'env$.nlmixr2Dots'). If it returns a non-'NULL' value that value becomes the fit – the interceptor has *claimed* the estimation; if it returns 'NULL' it declines and the next interceptor (or the standard method) runs. While a claimed interceptor runs, interceptors are suppressed, so it may call 'nlmixr2()' internally and get the ordinary methods.

Usage

registerEstInterceptor(name, fun)

removeEstInterceptor(name)

Arguments

name	unique interceptor name.
fun	'function(env)' returning a finalized fit to claim, or 'NULL'.

Value

invisibly the function (register) or 'TRUE'/'FALSE' (remove).
