我想基于两列生成索引以对观察进行分组.但是我希望小组能够通过观察来共享,至少有一个公共观察.我可以看到如何根据共同观察的观察结果制作小组,而不仅仅是其中一个.

例如,使用数据框:

dt <- data.frame(id=1:10,
             G1 = c("A","A","B","B","C","C","C","D","E","F"),
             G2 = c("Z","X","X","Y","W","V","U","s","T","T"))

我想得到一个专栏

1,1,1,1,2,2,2,3,4,4

我尝试使用dplyr中的group_indices,但还没有管理它.
