一个示例/测试数据看起来像下面这样。“dyad”是一组2个人在讨论“post”中互相交谈（1行= 1条消息）。这些观察结果是按时间顺序排列的。

structure(list(post = c(1, 1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 3), 
    dyad = c("111_222", "111_222", "111_222", "222_345", "333_567", 
    "333_899", "333_990", "435_123", "435_555", "435_123", "435_111", 
    "435_555")), class = "data.frame", row.names = c(NA, -12L
), codepage = 65001L)

我尝试创建的是两个变量：“响应1“和“响应2”。
*回答1：（a）不同于焦点二单元组（行）的不同二单元组的数目，其中（b）在一个post内的焦点二单元组（c）**之前。

• response 2：这只是帖子中焦点对的顺序。

结果可能如下所示：

+------+---------+-----------+-----------+
| post | dyad    | response1 | response2 |
+------+---------+-----------+-----------+
| 1    | 111_222 | 0         | 1         |
+------+---------+-----------+-----------+
| 1    | 111_222 | 0         | 2         |
+------+---------+-----------+-----------+
| 1    | 111_222 | 0         | 3         |
+------+---------+-----------+-----------+
| 1    | 222_345 | 1         | 4         |

+------+---------+-----------+-----------+

+------+---------+-----------+-----------+
| 3    | 435_123 | 1         | 3         |
+------+---------+-----------+-----------+
| 3    | 435_111 | 2         | 4         |
+------+---------+-----------+-----------+
| 3    | 435_555 | 2         | 5         |
