[igraph] Pajek Files

[Lorenzo Isella]

Dear All,
I am given some pajek files to read (I do not really have much of a 
choice about the input format).
I had a look at the documentation at

http://bit.ly/9oyBKJ

However, there is one point that is unclear to me. The pajek file also 
contains the (probably normalized in [0,1]) coordinates of each node 
i.e. the graph layout.
My point would be to read that graph and, among other things, be able to 
plot it as a pdf with the input-specified layout and possibly the 
suggested colors.
How can I do that (possibly using the R interface)?
To fix the ideas, please have a look at the pajek file which I paste below.
Many thanks

Lorenzo
