Get a single target from a potentially time-varying target design

In most cases, the target design will just specify a single target. But in some scenarios, a time-varying target may make sense. In that case, for each regimen update instance, a different target can be specified. This function just grabs the right target values from the overall target design. If just a single target is specified, it will just return the target design as-is.

Usage

get_single_target_design(target_design, idx = nrow(target_design$scheme))

Arguments

target_design

target design, created using create_target_design.

idx

number of regimen update. By default it will take the last instance.
