There seemed to be some problems with downloading the namespaced ‘network’ from my webstite (thanks Neil!). File permissions were set incorrectly. I fixed that and everything should be OK now.

Because it’s Friday, another example of using ‘intergraph’. This time plot a network using both ‘igraph’ and ‘network’ functionality on the *same *plotting device. Here is the result:

And here is the code to produce it. `lx`

in line 12 is “Deus Ex Machina”, or rather “Deus Ex locator()”…

# rescale 'x' to [-1; 1] res <- function(x) { a <- -1 - (2*min(x))/(max(x)-min(x)) b <- 2 / (max(x) - min(x)) a + b*x } op <- par(mar=rep(0.5,4)) net <- as.network(exIgraph) # using 'intergraph' set.seed(12345) k <- apply(layout.fruchterman.reingold(exIgraph), 2, res) lx <- c(-0.5, -1) k2 <- sweep(k, 2, lx, "+") plot(exIgraph, layout=k, rescale=FALSE, xlim=range(rbind(k, k2)[,1]), ylim=range(rbind(k, k2)[,2]) ) plot(net, coord=k2, displaylabels=TRUE, label=net %v% "label", new=FALSE) par(op)
