hi all, i am trying to plot a network LD figure using netGWAS. this is the code i use but the figure doesn't make any sense..

res <- netmap(data, method = "npn", cross= "inbred", rho = NULL, n.rho = NULL,
   rho.ratio = NULL, min.m= NULL, use.comu= FALSE, ncores = "all",
   em.iter = 5, verbose = TRUE)
plot(res, label.vertex="all", vertex.size = 7, w.btw = 150, label.size = 0.1)

any help will do! thanks
