在rmarkdown中编织到html flex_dashboard时出现以下错误。
UseMethod（“ mutate_”）中的错误： 没有适用于“ mutate_”的适用方法应用于“函数”类的对象 调用：... withVisible->-> mutate-> mutate.default-> mutate_ 执行停止
收到此错误很奇怪，因为我看不到自己的错误。我在做什么错了？

我不确定，但是我想您忘记了在文件中包含df吗？在我的情况下，以下另存为test.Rmd的脚本起作用了：

重要提示：Rmd确实很难调试。如果仍然遇到问题，只需在控制台中逐行运行代码即可。

您可以一次尝试下面的代码
```{r include = FALSE}
# create promodata
df2<-df %>%
mutate(promo_active = if_else((datum_besteld >= datum_start_promo &
datum_besteld <= datum_end_promo), 1, 0, missing = NULL),
weekday = weekdays(datum_besteld),
weekend = if_else(weekday == "Saturday" | weekday == "Sunday", 1, 0, missing = NULL)
)
df2
```
