Simone,
thanks for reporting this, it is actually a bug.
To correct it you can modify line 1940 in src/foreign-pajek-parser.c
from
{ igraph_pajek_directed=0; }
to
{ igraph_pajek_directed=1; }
I can send you a corrected R package (source or binary) if you
don't build R from source or don't know how to do the change above.
Another (dirty) workaround would be
g[[2]] <- TRUE
after reading the graph from the file. I think this works for the
0.3.3 version, it definitely won't work from 0.4. I've tried for the
.net file you've sent, it works for that. But this is a very dirty
thing since it assumes that igraph stores the edges in exactly the
same order as in the .net file.
Thanks,
Gabor

btw, can you tell me also why, after importing the net file, I have:
is.directed(g)
[1] FALSE
while the .net file represent a directed graph?
sorry to trouble you with this silly questions, but I would like to
learn igraph, cause it seems the smartest way to use R for quite
medium network (I am studying an online community made by 800
nodes)..
thank you,
Simone
