[igraph] edge attribute indexing in R

[Michael Barnett]

Hi igraph list,

New igraph list member here. I wanted to write to ask if anyone else  
has encountered this issue. I'm using R 2.10 in Mac OS 10.5.8.  
Whenever I try to index an igraph network object by an edge attribute,  
R is incredibly slow for the large-ish networks I'm working with, on  
the range of hundreds to thousands of nodes. I use the exact notation  
in the help file, typing for instance:

E(net)[ weight < 1.5]$weight

This code works for me when I make simple test networks, but not for  
the larger datasets I'm working with. R becomes slow enough that I  
have to force exit the program after becoming impatient after a few  
minutes. Has anyone else encountered this issue? Is this a known bug?
