expt <- ClinicalExperiment(number.of.factors = 3,
                           number.of.factor.levels = c(2, 2, 3),
                           number.of.treatments = 3)
r.obj <- new("PocockSimonRandomizer", expt, as.integer(12345))
r.obj <- randomize(r.obj, "Subject-001", c("1","2","2"))
## Try once again with same subject and you should get an error
## r.obj <- randomize(r.obj, "Subject-001", c("1","2","2"))
## Or try with a bad factor value and you should get an error
