[R] Neural Net Validation Sub Set

[Matthew Oliver]

Dear R users,
I have been playing with the nnet and predict.nnet functions and have two questions.

1) Is it possible to specify a validation set as well as a training set in the nnet 
function before using predict.nnet to test the nnet object against new data?

2) Is it possible to specify more than one layer of neurons?

Thanks in advance
