I am using Vinecopula package to make Trees in R vine. The distance between the edges is very small and nodes are overlapping. I tried tkplot, plot.igraph and even tried changing bigpar(2,3) but there is always error or the Chunk hangs. I am attaching the image I am getting. I need clear image with long edges and non overlapping nodes.
bigpar(2,3)
junk<-fit.rv.sum.mle$RVM
junk[[7]]<-c("Roil" , "Rdollar", "Rbond", "Rgold", "Rcommo" , "Rsp1200", "Requity")
plot(junk,tree="ALL",edge.labels="family-tau",type=1)
