r - 使用 mutate() 返回关于无法修改的错误，因为它是一个分组变量

Error in mutate_impl(.data, dots) :
  Column `month` can't be modified because it's a grouping variable

我想绘制一个轴是一年中的月份，但是我希望它从八月到七月。我还希望“周”显示 1-5 而不是 5-1.....但是当我尝试以下代码时它不允许我这样做:

Admit_Weekly1 <- Admit_Weekly %>%
+   filter(Retention_Status == 1) %>%
+   mutate(week = factor(week,levels(week)[1,2,3,4,5])) %>%
+   mutate(month = factor(month,levels(month)["August","September","October","November",
+                                             "December","January","February","March",
+                                             "April", "May","June","July"]))

mutate_impl(.data, dots) 中的错误:
week 列无法修改，因为它是一个分组变量

最佳答案

我遇到了同样的问题并使用 ungroup() 解决了它:

df <- df %>%
ungroup(var) %>%
mutate(var = factor(var,levels = c(1,2,3),
                    labels = c("label1","label2","label3") ) )
