Examples

(x = clinfun::ph2simon(pu = .2, pa = .4, ep1 = .05, ep2 = .1)) 

# an alternative print
print_ph2simon(x)

# language for a report
Sprintf.ph2simon(x, type = 'minimax')
Sprintf.ph2simon(x, type = 'optimal')
Sprintf.ph2simon(x, type = 'n1')
Sprintf.ph2simon(x, type = 'maximax')

autoplot(x, type = 'minimax')
autoplot(x, type = 'optimal')
autoplot(x, type = 'n1')
autoplot(x, type = 'maximax')

# operating characteristics
simon_oc(prob = c(A = .3, B = .2, C = .15), object = x, type = 'minimax')
simon_oc(prob = c(A = .3, B = .2, C = .15), object = x, type = 'optimal')

# example with r1 = 0
(x1 = clinfun::ph2simon(pu = .05, pa = .3, ep1 = .05, ep2 = .2))
# works with all of our functions
autoplot(x1, type = 'optimal') # etc.
