Re: [igraph] building R package from development branch igraph--main--0.4

[Gabor Csardi]

Vincent, 

thanks a lot for the testing! It is very useful. One tip:
please always run simplify the graph with 'simplify' to remove 
the loop and multiple edges from the graph, i think most algorithms
assume that the graph is simple. 

As for the windows filenames, hmmm, i never experienced this, but 
plan to compile a windows R package today, so we will see what happens.
I'll put the package to the same place if you're interested, there were
not too many changes since the last version, most notable is perhaps 
a completely new fastgreedy implementation by Tamas and a (premature) 
GML file reader, it does not read the attributes yet, only graph 
structure, i'll add attributes soon. The windows binary package 
whould be on the website before tomorrow.

Thanks again, 
Gabor
