Thesis Heston-Nandi model implementation

[Julianlapoutre]

   Hello,
   
   i'm working on my master thesis and i would like to implement heston-nandi model.
   The idea is to use BS as benchmark to compare how HN-GARCH is better to estimate option price. And i would like to use another Garch process like EWMA to see if it's still better than BS model.
   
   So i have found R Package named "fOptions" http://cran.r-project.org/web/packages/fOptions/fOptions.pdf but i have never used R before and i don't have quantitative and programming back ground.
   
   So i would like to know if you know an easier way to do this work ?
   Do you think i should simulate a serie or use real data ? (i mean it will be easier to compare which model fit the real price) ?
   
   Thanks for help
