Edges not visible in RStudio viewer or Zoom

[ZedLeb]

Hi Bryan - or any other kind soul who could shine a light...

I've come across your package today via www.kateto.net/polnet2017 superb tutorial on networks. I have used visNetwork up until now and haven't really go to grips with igraph notation - but willing to try now! So I kind of jumped in at the deep end and installed threejs too.

Following Ms Ognyanova's code I got a lovely interactive graph that rotated beautifully - except I saw no edges. So I went to your pages and took the simplest bit of code

suppressPackageStartupMessages(library(threejs, quietly=TRUE)) 
data(LeMis) 
graphjs(LeMis, vertex.size = 1)

and got exactly the same result...nodes a plenty but no edges. I can see from your output how it should look.

I have no errors reporting but attach my sessioninfo in case someone can see some kind of conflict...

If anyone has any suggestions - most gratefully received - I think this is a beautiful package and I really want to advance with it.

Many thanks
Zoe

Hi Zoe,

There is a little "pop out" button in the RStudio viewer window (if you hover over it, it says 'Show in new window'). Can you try pressing that?

This will open your plot in a web browser window. The network may properly render there.

We have seen miscellaneous problems with RStudio's rendering engine especially on Windows machines. Fortunately, RStudio is often updated and I expect things to eventually render properly. Until then, you might need to use the pop out visualization on your machine.

Let me know if this works...

I'm running things OK in recent versions of RStudio now, is that also the case for you?

Try setting the vertex attributes of your igraph object.

Example:

g <- graph_from_data_frame(df)

V(g)$size <- 10
V(g)$color <- 'red'

graphjs(g)
