[R] Neural Network

[javad bayat]

Dear all;
I am the new user of R. I want to simulation or prediction the Eutrophication of a lake. I have weekly data(almost for two years) for Total phosphorus, Total N, pH, Chlorophyll a, Alkalinity, Silica.
Can I predict the Eutrophication by Neural Network in R?
How can I simulation the Eutrophication by these parameter? 
please help me to write the codes.
many thanks.
