Question

我的数据集如下，我想创建一个网络但错误是我的邻接矩阵不对称，我是R新手，我不知道如何将我的数据转换为对称邻接矩阵，可以吗？请一位帮助我？

df2:
17  "RobertKennedyJr" "RobertKennedyJr "             
18  "Real_Sheezzii"   "Real_Sheezzii "               
19  "Kellie_Martin"   "Kellie_Martin "               
20  "ThatsOurWaldo"   "ThatsOurWaldo "               
21  "SCN_Nkosi"       "SCN_Nkosi "                   
22  "azsweetheart013" "azsweetheart013 "             
23  "KYourrights"     "KYourrights KathyConWom"      
24  "GowTolson"       " KathyConWom"                 
25  "Peterpu52451065" " KathyConWom"                 
26  "Jifchoppa"       " KathyConWom"                 
27  "ClaraLpz3"       " KathyConWom"                 
28  "Anna5705"        " KathyConWom"                 
29  "Brizzle254"      " KathyConWom"                 
30  "JackSpa02102454" " KathyConWom"

我尝试过的代码

library("igraph")
library("network")
library("statnet")
relationsp <- as.matrix(df2)
relationsp



net <- as.network(x = mat, # the network object
                  directed = TRUE, # specify whether the network is directed
                  loops = FALSE, # do we allow self ties (should not allow them)
                  matrix.type = "adjacency" # the type of input
)

如果你应用igraph包，你应该使用graph_from_data_frame来创建图对象net，然后使用get.adjacency来获取邻接矩阵，例如，

> net <- graph_from_data_frame(dat)

> get.adjacency(net, sparse = FALSE)
