Here is my example again:

g <- graph.ring(10)
E(g)$weight <- c(1,2)
coords <- layout.fruchterman.reingold(g, weights=E(g)$weight)

The coordinates are in 'coords'. layout.fruchterman.reingold() does
_not_ plot the data, it just calculates the coordinates. The plot()
function does the plotting. If you don't want to plot your graph,
don't call the plot() function.

Best,
Gabor
