QUESTION
In phyloseq, there is a plot called plot_net. The most basic plot_net plot code looks like this:
...ANSWER
Answered 2018-Nov-13 at 00:07I don't think there is a way to use NULL
in selectInput
. Here's an alternative which you almost worked out - Use "None"
(or any other replacement value) in selectInput
and switch it with NULL
while plotting. This way you don't have to write multiple if...else
.
QUESTION
I have created this application: https://usaskssrl.shinyapps.io/AnnualReport_2017_18/
I am trying to make a network dynamic visualization in R shiny (tab: Network Analysis, this takes a few minutes to load).
Everything looks like it works fine but there isn't any labels for the nodes.
I wasn't responsible for this part of the app but here is the code for your reference (can also be accessed through my repo- see link below)
Global.R (line 225):
...ANSWER
Answered 2018-Oct-03 at 11:59Well I found a work around.
I created the network animation and had the output be HTML. I hosted that animation online and pointed my app to that webpage. If you click on the "Network Analysis" tab you will see what I mean https://usaskssrl.shinyapps.io/AnnualReport_2017_18/ http://ssrl.usask.ca/documents/SSRL%20SNA%202017%20and%202018.html
For those interested, here is the code for the animation
QUESTION
I have a dynamic network which I want to represent with R shiny and visNetwork. Depending on the node which is chosen, colors of the nodes and edges should change according to some external protocol/data (nodeslist & edgeslist in the code below).
This works quite well for nodes: I select a node and in all future time steps the colors of the nodes change according to the data. For doing so, I use visUpdateNodes
.
But when I try to do basically the same for the edges with visUpdateEdges
, it doesn't work correctly: instead of only coloring the nodes, new nodes are created (with the correct colors).
A simple example is here:
...ANSWER
Answered 2017-Nov-15 at 15:01You have to set id
in edges data.frame
and so use it to refer to existing edges in visUpdateEdges
