plot_sub1_study_state: Plots the study state of a given subset design.

In OneArmPhaseTwoStudy: Planning, Conducting, and Analysing Single-Arm Phase II Studies

Description

Plots the study state of a given subset design displaying the already enrolled patients and the stopping rules for the given study.

Usage

plot_sub1_study_state(sr, enrolledPat = data.frame(ep1 = logical(), ep2 =
  logical()), r1, n1, r, s, n)

Arguments

sr	dataframe containing the stopping rules for the given subset design defined by 3 columns named "Enrolled_patients", "Needed_responses_ep1" and "Needed_responses_ep2". This way each row defines when the study has to be stopped for futility.
enrolledPat	dataframe defined by two boolean vectors named "ep1" and "ep2" indicating which patient had a response in the subset and superset endpoint.
r1	critical value for the first stage.
n1	sample size for the first stage.
r	critical value for the subset endpoint.
s	critical value for the superset endpoint.
n	overall sample size.

Examples

#Calculate a subset design.
sub1 <- setupSub1Design(alpha = 0.1, beta = 0.2, pc0 = 0.3, pt0 = 0.4)
design <- getSolutionsSub1(sub1)$Solutions[10,]
#Define the stopping rules according to the chosen design.
sr <- data.frame(Enrolled_patients = c(design$n1, design$n),
Needed_responses_ep1 = c(design$r1, design$r), Needed_responses_ep2 = c(0,design$s))
#Simulate 14 random generated outcomes.
tmp_ep1 <- rbinom(14,1, design$pc1)
tmp_ep2 <- tmp_ep1 | rbinom(14,1, design$pt1)
enrolledPat <- data.frame(ep1 = tmp_ep1, ep2 = tmp_ep2)
#Plot study state.
