Error plotting Wiki example 1

[Brian Davis]

I'm new to this so it's probably user error but when I try to plot Example 1 in the Wiki I get an error and I'm not sure how to proceed.

library(rgexf)

people <- data.frame(matrix(c(1:4, 'juan', 'pedro', 'matthew', 'carlos'),ncol=2))

relations <- data.frame(matrix(c(1,4,1,2,1,3,2,3,3,4,4,2), ncol=2, byrow=T))

g <- write.gexf(people, relations)

plot(g, EdgeType="curve")

Error in paste("http://", listenAddr, ":", listenPort, appListi$path, : cannot coerce type 'closure' to vector of type 'character'

Hi Brian,

I run your code without problems. What's wrong? My guess: it has to be related with the IDE that you are using.

Best,

Jorge

Thanks! That was it. It works in the RGui but not in RStudio! I'll file a bug report with them.

Seems to be an issue for our pal jbkunst! I'm having the same in Rstudio

Hi everybody!

I'm not sure what is happening. Anyway I think the plot.gexf function need an unrgent update. This function was developing before the glorious htmlwidgets, that means now we can use the next packages for plot gexf objects:

• http://www.htmlwidgets.org/develop_intro.html#example-sigma.js
• https://christophergandrud.github.io/networkD3/
• http://igraph.org/r/
• http://dataknowledge.github.io/visNetwork/

What do you think George? I think we can implement some of them and give a option argument like:

plot(gefxobject, package = "networkD3").

Regards.

Whatever you want to/have time for implementing! I already have an example with networkD3 in the github.com/gvegayon/twitterreport package

Ok, let's implement networkD3 and igraph packages, and then sigmajs beacuse the porformance using d3 with more than 100 nodes is not so good (http://stared.github.io/tagoverflow/?site=stackoverflow&size=100) ;).

I'll try give me some time the next week ;) to start with these implementations.

Awesome!
