多个转移矩阵的介数中心性计算

Question

我对如何解决这个问题有点迷茫。

例如，我有 2 个转移概率矩阵，我想将其转换为 2 个图并保存 2 个节点的中介中心性：3110 和 110。我想将结果保存在 2 个单独的 csv 文件中。这可以使用 igraph 完成吗？

我正在处理大型数据集。如何读入 R n csv 文件的数量 - 特定文件的位置 - 带有转换矩阵 b.) 从每个转换矩阵创建一个图； c.) 计算特定节点的中介中心性

Answer 1

你在追求这个吗？

> g1 <- graph_from_adjacency_matrix(as.matrix(df1[-1]), weighted = TRUE)

> g2 <- graph_from_adjacency_matrix(as.matrix(df2[-1]), weighted = TRUE)

> v <- c("3110", "110")

> betweenness(g1, v)
3110  110
  64   22

> betweenness(g2, v)
3110  110
  31    7

更新

如果你想保存到单独的文件中，也许你可以尝试

v <- c("3110", "110")
g <- list(g1,g2)
for (i in seq_along(g)) {
    write.csv(between(g[[i]],v),file = paste0("g_",i,".csv"))
}
