Одна из вещей, которые я пытался было
plot(factor(Gas.Source),MPG)
это именно то, что вы ожидали бы. Некоторые из уровней факторов имеют очень мало (или одно) наблюдений, и поэтому вместо того, чтобы ящик и whicker вы получаете черную линию.
Я понимаю, что это именно то, что я попросил об этом, поскольку некоторые из этих источников имели очень мало наблюдений. Итак, что бы я хотел сделать, это эффективно удалить измерения, связанные с уровнями факторов, где недостаточно наблюдений, чтобы действительно создать коробку и вискер ...
Я предполагаю, что смогу сделать это, создав новый dataframe, где я использовал логическую подписку для выбора только тех строк, которые соответствуют уровню фактора, который имеет счетчик больше X .... но я недостаточно изощрен, чтобы понять это.
Нет, вы не можете удалить уровни, которые имеют подсчет ниже определенного порога. Представьте себе ситуацию, когда есть 100000 отсчетов, но они все одинаковы. Вы получите то же самое «строка» без окна и усов –
Но вы можете удалить столбцы (факторы), где 'sd' намного ниже среднего' sd' по всем столбцам или значительно ниже следующего минимального ' sd' –
