r - 使用管道将数据类型更改为因子，但它不起作用

Question

刚刚开始使用 R。

我正在尝试将季节数据类型更改为因子并将其重新编码为适当的季节。但是我收到错误 f 必须是一个因子(或字符向量)

bikedf%>%
      mutate(season = as.factor(season))%>%
      fct_recode("Spring" = "1", "Summer" = "2", 
      "Fall" = "3", "Winter" = "4")

但是，当我不使用管道时它会起作用。

bikedf$season = as.factor(bikedf$season)%>%
  fct_recode("Spring" = "1", "Summer" = "2", "Fall" = "3", "Winter" = "4")

我不太明白为什么我的第一个代码不起作用。

Answer 1

%>% 应该位于 mutate 内，而不是在关闭 之后)

bikedf%>%
  mutate(season = as.factor(season)%>%
                   fct_recode("Spring" = "1", "Summer" = "2", 
                      "Fall" = "3", "Winter" = "4"))
