Javascript 使用中的clickAction将networkD3中的节点链接到网站

有没有一种方法可以使用r中networkD3包中的函数forceNetwork（）将节点用作指向外部网站的链接，但将其合并到shiny应用程序中

我找到了这个答案

但当我试图将它作为一个闪亮的应用程序运行时，它就不起作用了。 这是我的密码：

library(shiny)
library(networkD3)

source =c(0,0,3,3,3,7,7,10,9,7,1,6,4,5,8,2)
target = c(1,2,4,5,6,8,9,11,12,10,9,10,8,9,11,8)
value = c(10,10,10,10,10,10,10,20,20,10,2,2,2,10,20,15)
MisLinks = data.frame(source,target,value)


name = c("[Category]Genre", "CCG", "Action",  [Category]Art","Realistic Art", "Dark Art", "Cartoony", "[Category]Time  demend", "Mid-Core", "Hard-Core", "Casual", "Install", "Not Install")
group = c(1,2,2,3,4,4,4,5,6,6,6,8,8)
size = c(50,20,20,50,20,20,20,50,20,20,20,250,250)
hyperlink = c("http://google.com", "http://yahoo.com", "http://google.com", "http://yahoo.com", "http://google.com", "http://yahoo.com", "http://google.com", "http://yahoo.com", "http://google.com", "http://yahoo.com", "http://google.com", "http://yahoo.com", "http://yahoo.com")
MisNodes = data.frame(name, group, size, hyperlink)



ui = fluidPage(
titlePanel("Testing app"),

sidebarLayout(
sidebarPanel(
  sliderInput("opacity", "Test", 0.6, min = 0.1, max = 1, step = .1)
),
mainPanel(
  tabsetPanel(
    tabPanel("Force Network", forceNetworkOutput("force"))
  )
)
)
)

Myclickaction = "window.open(d.name, '_blank')"

server = function(input,output) {

output$force = renderForceNetwork({
forceNetwork(Links = MisLinks, Nodes = MisNodes,
             Source = "source", Target = "target", charge = -150, 
             legend = TRUE, opacityNoHover = 1, Nodesize = "size",
             Value = "value", NodeID = "name",
             Group = "group", linkWidth = 2, clickAction =  Myclickaction,
             opacity = 0.9, colourScale =JS("d3.scaleOrdinal(d3.schemeCategory20);"),
             zoom=t)


})
}
shinyApp(ui = ui, server = server)

期望的结果：在已发布的应用程序中单击节点时 您将在浏览器中打开一个新窗口，该窗口指向特定的网页，具体取决于所单击的节点

第10行的

[Category]Art

之前缺少一个报价

您在第44行传递的是

zoom=t

，而不是

zoom=t

这个

Myclickaction=“window.open（d.name，'.'u blank'）”

应该是第33行的

Myclickaction=“window.open（d.hyperlink，'.'u blank'）”

---

在第38行，将

forceNetwork

的输出保存到一个对象，以便以后可以修改它，如

fn Hey man！非常感谢，这解决了问题。我在尝试为stackoverflow设置格式时犯了所有语法错误，我写了这行：Myclickaction=“window.open（d.name，'.'u blank'）”，看看它是否可以传递诸如name之类的已知变量，这很有效，所以我猜这是因为forcenetwork默认情况下无法识别其他变量，但该死的家伙，你救了我，再次感谢！使用此方法，我们可以将不同的形状（矩形、三角形、正方形）添加到节点，而不是添加默认的圆。
