 ```***** To join INSNA, visit http://www.insna.org ***** Sebastian: Another interesting way is to use "statnet" in R. It is useful if you also want to generate various random networks with that degree sequence but general (ERGM) topography. Here is example code in R: #Create a network with the degree sequence library(degreenet) y <- reedmolloy(rep(1:4,c(2,6,8,4))) #Simple random draw from the set of networks with that degree sequence library(ergm) ys <- simulate(y ~ dsp(2), constraints=~degrees, theta0=0) summary(y ~ degree(0:5) + dsp(2)) plot(y) summary(ys ~ degree(0:5) + dsp(2)) plot(ys) #Random draw from the set of networks with that degree sequence #and a positive propensity for two-paths (2-stars or 2-dyadwise shared partners) library(ergm) ys <- simulate(y ~ dsp(2), constraints=~degrees, theta0=1) plot(ys) summary(ys ~ degree(0:5) + dsp(2)) Cheers, Mark ---------------------------------------------------- Mark S.
