addParType: Fill parameter names indexes in a data set

In NMsim: Seamless 'Nonmem' Simulation Platform

Fill parameter names indexes in a data set

Description

Add par.type, i, j to a data.table that has parameter already

Usage

addParType(pars, suffix, add.idx, overwrite = FALSE)

Arguments

pars	Table of parameters to augment with additional columns
suffix	Optional string to add to all new column names. Maybe except 'i' and 'j'.
add.idx	Add 'i' and 'j'? Default is 'TRUE' if no suffix is supplied, and 'FALSE' if a suffix is specified.
overwrite	Overwrite non-missing values? Default is 'FALSE'.

Details

'addParType()' fills in data sets of Nonmem parameter values to include the following variables (columns):

• parameter: THETA1 , OMEGA(1,1), SIGMA(1,1), OBJ, SAEMOBJ

• par.name: THETA(1), OMEGA(1,1), SIGMA(1,1), OBJ, SAEMOBJ

• par.type THETA, OMEGA, SIGMA, OBJ

• i: 1, 1, 1, NA, NA (No indexes for OBJ)

• i: NA, 1, 1, NA, NA (j not defined for THETA)

As a last step, addParameter is called with overwrite=FALSE. This fills parameter and par.name. Combined, if parameter is in pars, it is used. If not, par.type, i, and j are used.

In the provided data set, parameter is allowed to have thetas as THETA(1) (the par.name format). These will however be overwritten with the described format above.
