Set Covariate Values

Covariates specified in the system file using <CV:?> and <CVSET:?:?> will have their default values for a given parameter set. This function is a means to overwrite those values.

Usage

system_set_covariate(cfg, covariate, times, values)

Arguments

cfg

ubiquity system object

covariate

name of the covariate

times

list of times (system time units)

values

corresponding list of values

Value

Ubiquity system object with the covariate set

# Creating a system file from the mab_pk example
