 Hi Tamas,

Thanks for the interesting info, is there a more detailed documented list of  differences between the ports?
I find the R interface to be very fast to sketch an idea and gives me reasonable running time for O(n2) algos on small graphs (1000's of nodes), if only it exploited the dual-core!  And all the force-based plotting make everything so visually stimulating that I wouldn't want to lose that speedy feature. On the other hand python seems very contagious :)

Thanks and keep me posted,

It's up to Gabor, he's the boss here :) As for me, I don't have any

Both are more or less in sync with the current C core :) There are
some features which are provided by the R interface but not by the
Python interface (mostly because those are much easier to be
implemented in R than in Python - for instance, fitting of power
laws). Graph plotting in Python is a little bit unconvenient yet:
since Python does not feature a GUI, one must export the graph in SVG
format using the write_svg method and use an SVG viewer like Mozilla
Firefox. The next release of the Python interface will probably
include some GUI for plotting, but I'm still considering the possible
ways of implementation (for instance, the Cairo library).
