newb ie R кодер здесь. У меня есть столбчатая диаграмма с накоплением в базе R, которую я хотел бы изменить численно по типу вопроса (Вопрос 1 Предварительно, Вопрос 1 Пост, Вопрос 2 Предварительно, Вопрос 2 Пост, и т. Д. c.)
Это возможно, довольно простое исправление, но я не могу заставить функцию переупорядочения работать. Другие вопросы по переупорядочению не совсем подходят к моему решению. Может быть, переупорядочить - не правильный способ go об этом?
Прикрепил мой график и базовый код. Спасибо огромное! Я ценю вашу помощь.

### Double check the data frame
library(psych) # Loads psych package
headTail(Data) # Displays last few and first few data
str(Data) # Shows structure of an object (observations and variables, etc.) - in this case, ordinal factors with 4 levels (1 through 4)
summary(Data) # Summary of the number of times you see a data point
Data$`1Pre` # This allows us to check how many data points are really there
str(Data)
### Remove unnecessary objects, removing the data frame in this case (we've converted that data frame into a table with the read.table function above)
library(likert)
Data <- as.data.frame(Data) # Makes the tibble a data frame
likert(Data) # This will give the percentage responses for each level and group
Result = likert(Data)
summary(Result) # This will give the mean and SD
plot(Result,
main = "Pre and Post Treatment Percentage Responses",
ylab="Questions",
type="bar")
