Re: [igraph] Plotting graphs much slower in 0.6

[Gábor Csárdi]

Hi, 

thanks for your report. Please update to the latest igraph version (0.6.5), and try it with that. Thanks.

Hi, 

Did the plot.igraph function get much slower in igraph 0.6 (I'm using R 2.15.2 on a 2.6GHz Mac Mini)? With the codes below, I get the plot in 0.4 seconds in igraph0, but it takes > 17 seconds in igraph v0.6

I gather that the new framework has its benefits, so perhaps having a 'quick' version of the plot function in v0.6 would help?

### Compare speeds

library(igraph0)

r=erdos.renyi.game(100,p=0.1)

system.time(plot.igraph(r,layout=layout.circle))

detach(package:igraph0)

library(igraph)

r=erdos.renyi.game(100,p=0.1)

system.time(plot.igraph(r,layout=layout.circle))

Best,

Dai
