networkd3

问题 when I am ploting a directed graph with NetworkD3 , The edges are not directed , how can I fix it ? an Example : library(networkD3) data(MisLinks) data(MisNodes) forceNetwork(Links = MisLinks, Nodes = MisNodes, Source = "source", Target = "target", Value = "value", NodeID = "name", Group = "group", opacity = 0.8) I want the result to be directed This is the definetion of directed Graph: "A directed graph is graph, i.e., a set of objects (called vertices or nodes) that are connected together,

问题 I'm trying to display the value variables of nodes and links in a networkD3 forceNetwork diagram as tooltips. To do this, I am using Shiny with htmlwidgets and the external JS library Tippy. Here is what I have so far: library(shiny) library(htmlwidgets) library(networkD3) fn <- forceNetwork( Links = MisLinks, Nodes = MisNodes, Source = "source", Target = "target", Value = "value", NodeID = "name", Group = "group", opacity = input$opacity) tippyJS <- 'tippy(".node")' server <- function(input,

问题 Using forceNetwork from the networkD3 R package, how can I change the color of the text in the legend to white? My Code: library(networkD3) forceNetwork(Links = subLinkList, Nodes = subNodes, Source = "root", Target = "children", Value = "linkValue", NodeID = "nodeName", Nodesize = "nodeSize", Group = "nodeGroup", colourScale = JS(colorScale), charge = -500, opacity = 1, opacityNoHover = 1, fontSize = 25, fontFamily = "Calibri", linkDistance = JS('function(){d3.select("body").style(

问题 I would like to visualize some deeply nested data using networkD3 . I can't figure out how to get the data into the right format before sending to radialNetwork . Here is some sample data: level <- c(1, 2, 3, 4, 4, 3, 4, 4, 1, 2, 3) value <- letters[1:11] where level indicates the level of the nest, and value is the name of the node. By using these two vectors, I need to get the data into the following format: my_list <- list( name = "root", children = list( list( name = value[1], ## a

问题 I've am using sankeyNetwork in the networkD3 package to create a visualisation I would like to assign a name/ID to each edge, so that is appears in the tooltip. Can this be done with sankeyNetwork or any other function in the networkD3 package? 回答1: This is not technically supported, but you can achieve it like this... library(networkD3) library(htmlwidgets) links <- data.frame( src = c(0, 0, 1, 2), target = c(2, 3, 2, 4), value = 1, name = c("first", "second", "third", "fourth") ) nodes <-

问题 I would like to build a sankey diagram that highlights a path from end to end. I would like to use something free and that doesn't require me to upload data to do so. This Tableau visualization has exactly the functionality I want- when you hover over one link you can see the entire trajectory from start to finish without highlighting any other link that intersects with the same nodes and each of the link segments align cleanly: https://public.tableau.com/profile/actinvision#!/vizhome

问题 I am developing an R shiny application that uses several html widgets, notably networkD3 , d3heatmap and chorddiag . These widgets work fine separately. However, using them in the same page leave a blank space where they are supposed to be. Here is a reproducible code that shows the bug. Comment plots line in the UI and you will see plots appearing and disappearing.. I thank you very much for your help! # libraries library(shiny) library(d3heatmap) library(chorddiag) library(networkD3) #

问题 I want to implement a tooltip in Shiny-hosted networkD3 plot similar to the ggvis function, e.g: require(ggvis); require(shiny) all_values = function(x){ "<a href='#'>Option 1</a><br/><a href='#'>Option 2</a>"} server = function(input, output, session) { observe({ ggvis(mtcars, ~disp, ~mpg) %>% layer_points() %>% add_tooltip(all_values, 'click') %>% bind_shiny('ggvis_plot', 'ggvis_ui') }) } ui = fluidPage( uiOutput("ggvis_ui"), ggvisOutput("ggvis_plot")) shinyApp(ui, server) Is there an
