expand.idata: Create template data sets for simulation

In mrgsolve: Simulate from ODE-Based Models

Create template data sets for simulation

Description

These functions expand all combinations of arguments using expand.grid(). expand.idata() generates an idata set; the others generate a full data set. The result always has only one row for one individual. Use expand.evd() or evd_expand() to render NMTRAN names (e.g. AMT or CMT) in upper case.

Usage

expand.idata(...)

expand.ev(...)

expand.evd(...)

ev_expand(...)

evd_expand(...)

Arguments

...	passed to expand.grid().

Details

An ID column is added as if not supplied by the user. In the output data frame, ID is always re-written as the row number.

For expand.ev(), defaults also added include cmt = 1, time = 0, evid = 1. If total is included, then addl is derived as total-1. If tinf is included, then an infusion rate is derived for row where tinf is greater than zero.

ev_expand() is a synonym for expand.ev() and evd_expand() is a synonym for expand.evd().

Value

A data frame containing one row for each combination of the items passed in .... The result always has ID set to the row number.

Examples

idata <- expand.idata(CL = c(1,2,3), VC = c(10,20,30))

doses <- expand.ev(amt = c(300,100), ii = c(12,24), cmt = 1)

infusion <- expand.ev(amt = 100, tinf = 2)
