Итак, что мне теперь делать? Как я могу решить эту ошибку? Ошибка в plot.window(...): нужны конечные значения "xlim" Кроме того: Предупреждающие сообщения: 1: In min (x): отсутствие непустых аргументов до min; возвращение Inf 2: В max (x): нет аргументов без пропуска до max; возвращение -Inf Если это возможно, исправьте мой код. Я не очень хорошо знаком с Rstudio и R.
