nw2fromedge problem

[kristian svendsen]

Thanks for a really neat and expansive stata package!

So  I have a dataset from wikipedia and I basically have ten articles (called substance) and all editors who have edited the articles (called user). There is a significant overlap between users editing different articles so there is a network here. With the nw2fromedge command I wanted to do the project(1) option to get the ten articles as nodes, but this fails with the following error after running this sequence:

keep  SUBSTANS USER

bysort SUBSTANS USER: egen test = count(1)

drop if test<4 //simply to get only the most important users for when testing this network, I have run this without this selection as well and still it fails

sort SUBSTANS USER

drop test

duplicates drop

nw2fromedge SUBSTANS USER, name(test99) project(1)

error I get back "Either option gen or option stub needs to be specified. invalid syntax"

Can you advice me on what is wrong?

kind regards

Kristian

Hi Kristian,

I cannot replicate your error. Can you send me a sample of your dataset and a syntax file directly to thomas....@gmail.com? 

I just ran the examples listed under . help nw2fromedge and they work.

Best,

Thomas
