### Examples

    ## load weather data
    data("WeatherPlay", package = "partykit")
    WeatherPlay

    ## construct simple tree
    pn <- partynode(1L,
      split = partysplit(1L, index = 1:3),
      kids = list(
        partynode(2L,
          split = partysplit(3L, breaks = 75),
          kids = list(
            partynode(3L, info = "yes"),
            partynode(4L, info = "no"))),
        partynode(5L, info = "yes"),
        partynode(6L,
          split = partysplit(4L, index = 1:2),
          kids = list(
            partynode(7L, info = "yes"),
            partynode(8L, info = "no")))))
    pn

    ## couple with data
    py <- party(pn, WeatherPlay)

    ## print/plot/predict
    print(py)
    plot(py)
    predict(py, newdata = WeatherPlay)

    ## customize printing
    print(py,
      terminal_panel = function(node) paste(": play=", info_node(node), sep = ""))
