r - 如何在不使用as_tbl_graph（）的情况下创建相同的结果？(how can I create identical result without using as_tbl_graph()?)

Question

My dataframe looks like this.

(我的数据框看起来像这样。)

Word1    Word2    Count
--------------------------
 a         b        4

 c         a        2

 b         c        1
-------------------------

I want the following result.

(我想要以下结果。)

from      to    count
-----------------------
  1       3       4

  2       1       2

  3       2       1

----------------------

I know I can achieve this easily using as_tbl_graph(df).

(我知道我可以使用as_tbl_graph（df）轻松实现这一目标。)

But I want this result only using base r code without using other packages.

(但是我只希望使用base r代码而不使用其他软件包来获得此结果。)

How can I create identical result without using other packages such as igraph, ggraph, tidyverse ...?

(如何在不使用igraph，ggraph，tidyverse等其他软件包的情况下创建相同的结果？)
