[R-SIG-Finance] Errors with Quanstrat-IV Demo

[George Chang]

Guy and Interested R-SIG Finance Members,

FYI, I was able to successfully run all of Guy's demo scripts that were
updated at: www.r-programming.org/papers.

I plan to study Guy's presentations and his approach with R scripts and
with luck,  develop my own strategy in the next few months. Many thanks to
Guy for his excellent slides and demo scripts.

Regards,
George Chang
