R networkD3 custom node color for radialNetwork()

由 一个人想着一个人 提交于 2019-12-11 17:25:18
问题 The R package networkD3 provides an interface for R users to make network plots in D3, but the input data and ability to map data to network aesthetics differs over the available plots (e.g., simpleNetwork, forceNetwork). Recently I've been trying to apply custom colors to each node in a radialNetwork(), similar to this thread, but I can't figure out how the custom coloring was mapped to the nodes. The code to produce a custom coloring: library(networkD3) library(tidyverse) library(data.tree)

Reactive height for sankeyNetworkOutput from networkD3

由 梦想的初衷 提交于 2019-12-11 10:59:36
问题 I have a Shiny dashboard that is displaying a sankeyNetwork from the networkD3 package. I'm creating the sankeyNetwork inside of a renderSankeyNetwork function on the server and then calling it on the ui with sankeyNetworkOutput. I'd like to make the height of the created sankeynetwork be dependent on a height value I've created. I tried using renderUI with uiOutput to run the sankeyNetworkOutput on the server, but it doesn't seem to be working. The dashboard works otherwise but there is

Sankey Diagram with R library networkD3 does not show colors

由 帅比萌擦擦* 提交于 2019-12-11 07:14:17
问题 I am using the networkD3 library for R in order to create Sankey networks. While this works pretty well for me, I have now encountered an issue with assigning the attributes "NoteID" and/or "NoteGroup" to group and allocate colors as shown in https://christophergandrud.github.io/networkD3/#sankey The following code shows 4 examples of creating a Sankey diagram, only "Sankey4" works as designed, i.e., no colors: library(networkD3) #Unique list of nodes my_nodes = structure(list(name = c(

Also, is there a way to adjust the font style and size of the title text as

Extracting node information from networkd3 to a reactive variable in shiny

由 匆匆过客 提交于 2019-12-08 10:17:36
问题 I am having a hard time working with networkd3 package in Shiny. I have plotted a graph and would like to extract node information back to shiny in a reactive manner to visualize more information concerning a certain node. E.g star graph with center node "Father" and other "Son1"..."SonN". Upon clicking on the Son node I would like to be able to access the "Son1" name in shiny to extract information from a data frame within shiny and visualize additional information (e.g job, age and so on).
