Data I have:
| A | B |
|---|---|
| 1 | a |
| 2 | c |
| 2 | e |
| 3 | f |
| 4 | h |
| 5 | c |
| 5 | e |
What I want:
如果A的不同组中B的所有值匹配，那么它们在同一组中.在这种情况下，所有B值(c和e)都匹配2和5.
| A | B | Group |
|---|---|---|
| 1 | a | 1 |
| 2 | c | 2 |
| 2 | e | 2 |
| 3 | f | 3 |
| 4 | h | 4 |
| 5 | c | 2 |
| 5 | e | 2 |
Code I attempted:
library(readxl)
library(dplyr)
library(stringr)
data1 <- read_excel("testing.xlsx")
data2 <- data1 %>%
group_by(A) %>%
group_by(B) %>%
mutate(Group = cur_group_id()) %>%
ungroup()
What I’m getting from this code:
| A | B | Group |
|---|---|---|
| 1 | a | 1 |
| 2 | c | 2 |
| 2 | e | 3 |
| 3 | f | 4 |
| 4 | h | 5 |
| 5 | c | 2 |
| 5 | e | 3 |
