Please ask appropriately (we pointed you to the posting guide dozens of 
times now)!

- We do neither have trn3 nor r.v
- Which function nnet() are we talking about? Do you meant the one from 
package nnet in the VR bundle?
- Which version of R and nnet are we talking about?
- What about trying to debug yourself in a first step? E.g. a 
traceback() might give you (and us) some first hints what is going on.
