r - 链接指向 forceNetwork 的左上角，R 中的 networkD3

Question

我正在尝试使用forceNetwork，但链接指向左上角并且链接不符合预期。

library(tidyverse)
library(networkD3)

nodes <- data.frame(name=c("H2o","H2O Driverless AI ","DAI","This is a Mechanized Operations Tracking System","H2O.ai","H2O","H2O is open-source software for Big Data analysis"),group = 1)

nodes <- nodes %>% rowid_to_column("id")

nodes_d3 <- mutate(nodes, id = id - 1)

links <- data.frame(source=c(0,1,2,0,4,5),target=c(1,2,3,4,5,6))

forceNetwork(Links = links, Nodes = nodes_d3, Source = "source", Target = "target", 
              NodeID = "id",Group = "group", opacity = 0.8,arrows = TRUE, zoom = TRUE)

预期结果是将 h20 作为节点 0，然后连接到“H2O Driverless AI”和 H2O.ai。然后 H2O Driverless AI > DAI。然后DAI>这是一个机械化操作跟踪系统。H2O.ai>H2O。H2O>H2O 是用于大数据分析的开源软件

如果我错了，请纠正。

鉴于您的数据，您可能应该使用NodeID = "name"

更新：

您还必须设置Value参数。这是一个可重现的例子......

library(tidyverse)
library(networkD3)

nodes <- data.frame(name=c("H2o","H2O Driverless AI ","DAI","This is a Mechanized Operations Tracking System","H2O.ai","H2O","H2O is open-source software for Big Data analysis"),group = 1)

nodes <- nodes %>% rowid_to_column("id")

nodes_d3 <- mutate(nodes, id = id - 1)

links <- data.frame(source=c(0,1,2,0,4,5),target=c(1,2,3,4,5,6), value = 1)

forceNetwork(Links = links, Nodes = nodes_d3, Source = "source", Target = "target", 
             Value = "value", NodeID = "name", Group = "group", opacity = 0.8,arrows = FALSE, zoom = TRUE)
