The (not yet finished) 0.6 version of igraph has weighted betweenness,
I think this is the same as the measure in Newman's paper. You just
need to calculate the weights of the edges and call betweenness().

You can download an R source package from here:

and an R package for windows from here:

Version 0.6 also has weighted closeness, and this looks the same to me
as Fowler's measure of 'connectedness'. Again, just calculate the
weights, and then call closeness().
