Hi R users

I'm running simulations of an index's returns (lets say S&P 500) and I
wonder of how good are the simulations.
 I thought that a good way to check It is performing a backtesting but I'm
a begginer in this issue so I don't know how to do it?

Could anyone recommend me a good backtesting function (or package) ??

Thanks in advanced.

Jaimie
