Dear all,
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.
set.seed(31)
V=letters[1:5]
g2=randomEGraph(V,0.5)
plot(g2,"neato",main="All weights 1","All weights are 1.")
# change and edge weight
edgeData(g2, from = "d", to = "e", attr = "weight") <- 20
plot(g2,"neato",main="Nothing changed!")
#try out length attribute change
edgeDataDefaults(g2,"len")=1
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 ?
Best
