Backtest trading strategies

Has anybody ever implemented a trading strategies backtest program on R?  Or
succesfully linked R to an existing backtest software? I'd like to know what
has been/can be done.

This is an area we have explored quite a bit. We took the approach of
using several tools, each for its own strengths. MySQL for data
storage and retrieval, Python for system creation/calculation, R for
results analysis and gnuplot for visual display. This has proved to be
a very powerful nexus and is the thrust of the Crusher project.

Here are the links to the tools we use. All open source!
