R中的coplot或散点图的月份排序

Question

给定一个数据帧 df 如下：

df <- structure(list(country = structure(c(4L, 4L, 4L, 4L, 4L, 4L, 
1L, 1L, 1L, 1L, 1L, 1L, 7L, 7L, 7L, 7L, 7L, 7L, 6L, 6L, 6L, 6L, 
6L, 6L, 9L, 9L, 9L, 9L, 9L, 9L, 8L, 8L, 8L, 8L, 8L, 8L, 5L, 5L, 
5L, 5L, 5L, 5L, 3L, 3L, 3L, 3L, 3L, 3L, 2L, 2L, 2L, 2L, 2L, 2L
), .Label = c("Hong Kong", "Indonesia", "Korea", "Mainland China", 
"Malaysia", "Singapore", "Taiwan", "Thailand", "Vietnam"), class = "factor"), 
    month = structure(c(3L, 2L, 5L, 1L, 6L, 4L, 3L, 2L, 5L, 1L, 
    6L, 4L, 3L, 2L, 5L, 1L, 6L, 4L, 3L, 2L, 5L, 1L, 6L, 4L, 3L, 
    2L, 5L, 1L, 6L, 4L, 3L, 2L, 5L, 1L, 6L, 4L, 3L, 2L, 5L, 1L, 
    6L, 4L, 3L, 2L, 5L, 1L, 6L, 4L, 3L, 2L, 5L, 1L, 6L, 4L), .Label = c("April", 
    "February", "January", "June", "March", "May"), class = "factor"), 
    tourist_arrivals = c(400.16, 28.78, 3.12, 0, 0, 0, 3207.802,

我用scatterplot(tourist_arrivals ~ month|country, data = df)或coplot(tourist_arrivals ~ month|country, type = 'b', data = df)画了一个散点图，但是如你所见，month的顺序不对，请问如何排列？

谢谢。

Answer 1

您可以使用

library(tidyverse)

df %>% 
  mutate(month =  factor(month, levels= c("January", "February", "March", 
                                             "April", "May", "June"))) %>% 
ggplot(aes(x = month, y = tourist_arrivals)) + 
geom_boxplot()

要获得 scatterplot 正确的月份顺序，您可以使用

library(car)
df1 <- df %>% 
  mutate(month =  factor(month, levels= c("January", "February", "March", 
                                          "April", "May", "June"))) 

scatterplot(tourist_arrivals ~ month|country, data = df1)

同样的方法你可以试试

coplot(tourist_arrivals ~ month|country, type = 'b', data = df1)
