如何同时使用 `group_by` + `rename`
原文 How to do group_by() + rename() at the same time
TIL (technically, it's not *today*. But I found this in my notes last semester, and I think it's worth sharing):output$tbl2 <- renderDT(
hwm %>%
group_by(
State = stateName,
Type = hwm_environment) %>%
summarize(...)
This is a very useful trick. It’s a bit like dplyr::rename, but it’s more flexible. You can use it to rename columns, while grouping by one or more columns.

TIL（技术上这不是今天的。但是我在我的课件上最近找到了这个，所以我觉得值得分享）：
output$tbl2 <- renderDT(
hwm %>%
group_by(
State = stateName,
Type = hwm_environment) %>%
summarize(...)
这是一个非常有用的技巧。它就像 dplyr::rename 一样，但是更灵活。你可以使用它来重命名列，同时分组一个或多个列。
