我有一个月份(数字)列表,我转换为名称:

fd <- df %>%
  select(product, sales, month) %>%
  mutate(month = month.name[month]) %>%
  filter(!is.na(product), sales!=0) %>%
  group_by(month) %>%
  summarise(sales = sum(sales)) %>%
  collect()

我想对表格进行排序,以便按时间顺序列出月份.我正在寻找一个解决方案与arrange()来自dplyr如果可能的话.

结果如下fd:

       month   sales
1      April 1306629
2     August 1317986
3   December 1263070
4   February 1493914
5    January 1316889
6       July 1323161
7       June 1331614
8      March 1439019
9        May 1369881
10  November 1256950
11   October 1317647
12 September 1229632
