Hi All,
I have no idea what changed, but now it all works. It seems that I had to
exit R and reload it, not just reload the source, after I replaced the input
file. Is there some caching going on?
Certainly not by igraph. If you open the file in R, replace it, and
then read from it in R, AFAIK R is still reading the old contents.
(Although this might be platform dependent and I don't know which
platform you are using.)

Apologies for wasting your time, and thanks a lot!

Works fine on OSX as well, igraph 0.5.4, R 2.11.1.

Hi again,
It works for me in igraph 0.5.3 as well (R 2.11.0, igraph 0.5.3, Linux).

Hi All,
I am experiencing a problem reading a pjek formatted graph (that I
output from my own conversion script). The graph opens fine in Pajek
itself.
I get the following error:
Fehler in read.graph.pajek(file, ...) :
At type_indexededgelist.c:245 : cannot add edges, Invalid vertex id
It is a very simple graph with no fancy attributes, just :
*Vertices 8309
1
2
3
4
5
6
...
*Edges
1 2
1 7044
10 985
100 1901
...
I have output many other .net graphs and ingested them into igraph
without problems before, although from a different procedure and
input, so it must be something with the new input graph data I have,
I assume.
I made sure that the number of vertices is correct, they are
numbered from 1, sequentially, and ordered in the output, and I also
ordered the edges. I have no idea what could be the problem.
Is there a way to enable more verbose debug output from igraph in R,
so that I see which vertex number is the problem?
the two graphs are available here, if anyone wants to try...:
