我有以下数据框：

df <- data.frame(
  Code = c("a", "a", "a", "a", "a", "b", "b", "b", "b", "b"),
  Inst = c("Yes", "No", "No", "No", "No", "No", "No", "No", "No", "No"),
  Date = c(
    "2021-01-01", "2021-01-02", "2021-01-03", "2021-01-04", "2021-01-05", 
    "2021-01-06", "2021-01-06", "2021-01-06", "2021-01-09", "2021-01-10"
  )
)

我想应用dplyr::group_by到变量Code并过滤特定值 "Yes" 和 minimum Date，但我想保留不包含 Yes 值的组的所有观察结果。我试过了，filter(any(Inst == "Yes"))但这不起作用。

我想要这样的结果：

Code  Inst  Date
a      Yes  2021-01-01
b      No   2021-01-06
b      No   2021-01-06
b      No   2021-01-06
