N1 is a class that computes the n1 value of a design.
This can be used as a score in minimize.
Usage
N1(label = NA_character_)
# S4 method for class 'N1,TwoStageDesign'
evaluate(s, design, optimization = FALSE, ...)Arguments

the second-stage sample size.
Examples
n1_score <- N1()
evaluate(
N1(),
TwoStageDesign(70, 0, 2, rep(60, 6), rep(1.7, 6))
) # 70
#> [1] 70
