[igraph] R: vertex attributes

[wanderingaengus]

Sorry to waste the bandwidth.  I found what I was looking for in the igraph 
wiki.  Still have a couple of questions about 'paths' but it's best if I tackle 
them in more detail before further exposing my ignorance. :)

I've gone through the archives, but my apologies if I missed this issue: 

I have a file that contains the following data 

<list of vertex attributes > 
vertex_i vertex_i_attribute 
vertex_j vertex_j_attribute 
vertex_k vertex_k_attribute 
etc. 
<directed edge list> 
vertex_i vertex_j 
vertex_j vertex_k 
vertex_i vertex_k 
etc. 


that is, a typical edge list, but with vertex attributes included. 

My end goal is to find the list of paths of length 'n' and for each path, 
define it according to a list of vertex attributes. 

Skimming the manuals for igraph-python and igraph-R distributions, it seems 
possible to do this using the python version of igraph, but not the R version 
of igraph. Or am I missing something? 

Thanks in advance.

What is it exactly that you cannot do with R?
