No wonder, writing computer programs is not just typing in random
words and let the computer figure out what you are trying to do. At
least not yet.

But you already have that in "test.net", no?
It would help if you could tell us what you are trying to do. If you
decompose a graph to components, you get a list of graphs; do you want
to save each component in a separate file? Then do this (untested):
for (i in seq_along(compo)) {
write.graph(compo[[i]], file=paste(sep="", "new-", i, ".net"), format="pajek")
}
If you want to do something else, then please tell us.
