addLogEstimates: Add log estimates to a model

Description

Add log estimates to a model

Usage

addLogEstimates(ui, vars, extraLines = NULL, beforeCmt = NULL)

Value

rxode2 model with log estimates added (and possibly extra lines)

Arguments

ui

rxode2 model

vars

estimates to add they will be parameterized as:

var <- exp(lvar)

where var is the variable name in the model and lvar is the log transformed variable that will be estimated

extraLines

this is a list of additional lines to add to the model just after the variables are defined. It must be NULL or a list of language objects.

beforeCmt

if the model is compartmental you can specify the preferred names where the estimates and extra lines are added before

Examples

# Change the transformation of the PK model from cl to k

readModelDb("PK_3cmt_des") |>
  removeLinesAndInis(c("kel", "k12", "k21", "k13", "k31", "vc")) |>
  addLogEstimates(c("kel", "k12", "k21", "k13", "k31", "vc"))

# You can also label the parameters by using a named character
# vector with the names of the parameters representing the
# variables and the values representing the labels:

readModelDb("PK_3cmt_des") |>
  removeLinesAndInis(c("kel", "k12", "k21", "k13", "k31", "vc")) |>
  addLogEstimates(c(kel="elimination", k12="k12 constant",
                    k21="k21 constant",
                    k13="k13 constant",
                    k31="k31 constant",
                    vc="volume of central compartment"))
