Re: [igraph] make igraph charts wider

[Gábor Csárdi]

So this has nothing to do with making the plots wider, after all. Use graph.data.frame() to convert your data frame to an igraph graph.

it works with your example:

 

library(igraph)
g <- graph.ring(10)
png("ring.png", width=300, height=150)
par(mar=c(0,0,0,0))
plot(g, asp=0, margin=0)
dev.off()

but I have a data frame to work with:

 

App1 App2  cor

web  hr       3

hr    pp      4

etc

 

when I do this:

 

g<-graph.ring(tt)

I get this error:

 

Error in graph.ring(tt) :
  (list) object cannot be coerced to type 'double'

 

I need to grahp a data frame.

I tried the above layout type and bunch of other ones but still getting the circular output. I would like to make the chart wider so that it is easlity readable. Is there an option like xaxis max or antything to make this work?
