setting seed number for ergm in statnet R

Question

I want to set the seed number in ergm, so that my network analysis is reproducible, but when I run

main_sup <- ergm(supnet ~ edges + nodefactor("work") + 
                     nodefactor("income") + nodefactor("edu") + 
                     nodefactor("religious") + nodefactor("gender") + 
                     nodecov("age") + edgecov(kin_sup,"kinweight"), 
                 control.ergm(seed = 567))

I get this error:

Error in eval(e, parent.frame()) : object 'name' not found'

Answer 1

I realized that I forgot to name the control argument, as in:

control = control.ergm(seed = 567)
