Hi and what is wrong with e.g.
fit <- neuralnet(pH~station+month, data=yourdata) As I said I am not an expert in neural nets but here is some explanation how it works http://gekkoquant.com/2012/05/26/neural-networks-with-r-simple-example/ based on that after fitting you could do compute(fit, testdata) where testdata shall be station and month. However for time series it can be more appropriate something like ARIMA modelling.

What did you do for testing it? I am not an expert in neural networks but I do not see anything which prevents using your data in nnet.
