# NOT RUN {
  data(pima)
  pima.sample <- sample(nrow(pima), 0.75*nrow(pima))
  pima <- prim.data.prepare(pima)
  pima.model <- prim(class ~ ., data = pima[pima.sample,],
    peeling.quantile = 0.4, min.support = 0.4)
  pima.predict <- predict(pima.model, pima[-pima.sample,])
  pima.idx <- prim.box.index(pima.predict, pima)
