[R]: Pruning methods for Neural networks in R

I have been using nnet and I was wondering if there are any prunning
methods for a Neural Network that have been implemented in R or if
someone has written a script, for example, Network Information Criterion
(NIC), Optimal Brain Damage, Non-contributing units?
NIC was used by Murata et al. for determining the number of hidden units
in a ANN (IEEE Trans. Neural Networks, 5(6): 865-872).
I have found both AIC and BIC in R, but not NIC.

Does anyone have any suggestions as to how this can  be done in R?
I am training a network with 126 input variables.
