Add gradient to links in R networkD3::sankeyNetwork?












0















Within the R environment, is there any way to add gradients to links with user-specified colors within the networkD3::sankeyNetwork functions?



This repo expands on the functions of networkD3::sankeyNetwork, but it only seems to allow for the linkGradient parameter when the LinkGroup parameter isn't used, i.e. you can only use the gradient when all links are the same color. Unfortunately, I require LinkGroup to specify a different color for each link.



Here's a reproducible example of a Sankey diagram with user-specified colors for the links, but without the gradient that I'm trying to impose.



source = as.numeric(c("0", "0", "0", "0"))

target = as.numeric(c("1", "2", "3", "4"))

value = as.numeric(c("40", "10", "5", "20"))

group = c("red", "yellow", "green", "blue")

node = as.numeric(c("0", "1", "2", "3", "4"))

name = c("source", "red", "yellow", "green", "blue")



links = data.frame(source, target, value, group)

nodes = data.frame(node, name)



networkD3::sankeyNetwork(Links = links, Nodes = nodes, 

                         Source = 'source', 

                         Target = 'target', 

                         Value = 'value', 

                         NodeID = 'name',

                         units = 'UOM',

                         LinkGroup = 'group',

                         colourScale = JS('d3.scaleOrdinal()  

                        .domain(["miRNA","red", "yellow", "green", "blue"])

                        .range(["black", "red", "yellow","green","blue"])'))


Edit: Yes, there is a java option here, but I'm looking for a solution within the R environment, i.e. via R, not java. Further, that solution doesn't work well with heavily curved links. The aforementioned repo provides a much smoother gradient with curved lines. I don't know how to modify from there to allow for multiple colored links with a gradient.

  • Basically, it cannot be done in R, not directly anyway. networkD3 just passes the data and a few options into the JavaScript code. To achieve this, you would have to (heavily) modify the underlying JavaScript code.

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
