Группировка нескольких значений в один фактор в одном столбце в RStudio

Question

У меня есть набор данных, который содержит несколько городов и их регионов продаж в одном столбце, они неоднократно отображаются в этом столбце, поскольку они разделены следующими двумя столбцами типов продуктов и дат. Я уже преобразовал каждый регион в фактор:

avocadodata$Region <- factor(avocadodata$Region, levels = c("California","West","Plains","South Central","Great Lakes","Northeast","Midsouth","Southeast"), labels = c("California","West","Plains","South Central","Great Lakes","Northeast","Midsouth","Southeast"))

Затем используйте summary(avocadodata$Region), чтобы проверить и выяснить, были ли города NA's, потому что я не преобразовал их в факторы.

Как преобразовать города в один фактор, который также разделен на следующие два столбца: типы продуктов и даты? Поэтому я не получаю Na's в summary(avocadodata$Region)?

(Пожалуйста, проверьте набор данных, у вас будет представление об этом случае)
