igraph

I have created a graph and used the propagating labels community detection algorithm to detect subgroups in the graph. I have then plotted the graph and coloured the vertices according to their group membership using rainbow colours. Here is the code I used: g <- watts.strogatz.game(1, 100, 5, 0.05) clp <- cluster_label_prop(g) V(g)$community <- clp$membership rain <- rainbow(14, alpha=.5) V(g)$color <- rain[V(g)$community] plot(g, vertex.size=4, vertex.label=NA) I would now like to colour edges that lie between members of a subgroup in the same colour as that subgroup, in order to better

I'm using python 2.7 on 64-bit Linux Mint 16 and I'm trying to install python-igraph. But when I run sudo pip install python-igraph I get the following log: Downloading/unpacking python-igraph Downloading python-igraph-0.7.1-1.tar.gz (375kB): 375kB downloaded Running setup.py egg_info for package python-igraph Installing collected packages: python-igraph Running setup.py install for python-igraph Build type: dynamic extension Include path: /usr/include/igraph Library path: Linked dynamic libraries: igraph Linked static libraries: Extra compiler options: Extra linker options: building 'igraph.

How to change a color label node from its id or name? Ex: I want to change label color node name="4" or id=3 g9<- graph(c(0,1,0,2,0,3,1,4,1,2,3,4,3,5,4,5,5,2),n=6,dir=FALSE) V(g9)$name<-c(1:6) V(g9)$label<-V(g9)$name V(g9)$color is an array of colors. To change color of a specific node say 2: V(g9)$color[2] ="#343434FF" If you want different color for each node, you can specify rainbow(n) where n is number of nodes and this function generates a array of colors and then you can specify: V(g9)$color=rainbow(9) Also note: To get a list of vertices or nodes you can get them: V(g9) and then if you

I have problems to install python-igraph on the anaconda distribution of python. If I write pip install python-igraph (with the admin privileges) in the anaconda command, the installation doesn't work. Check the documentation on their site: http://igraph.org/python/ It says that you need to download the .msi installer, pip does not work under windows. That is probably because you need a C compiler and windows does not supply one by default. Jan Katins You can download a wheel installer from http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-igraph and then install that wheel in your environment
