[R] Rgraphviz - neato layout - edge weights do not have an effect

neato makes layouts according to a physical model in which the length of
the edges is determined by springs. The weight of the edge is the
strength of the spring. However, I was not able to find any influence of
edge weight on the layout. In the
http://www.graphviz.org/Documentation/neatoguide.pdf the attribute "len"
is another parameter of the neato layout.
plot(g2,"neato",main="All weights 1")
# change and edge weight
edgeData(g2, from = "d", to = "e", attr = "weight") <- 20
#try out length attribute change
edgeData(g2, from = "d", to = "e", attr = "len") <- 5
plot(g2,"neato",main="Nothing changed again!")
Has anyone an idea how to achieve a change in the graph layout ?
