Technical Pattern Trading (Should Head Should, etc.) in R?

Hi all,


I am trying to explore the technical pattern based trading strategies using
R.

One paper is of course Andrew Lo's:

Some googling showed some online blogs mentioning technical pattern
detection but without too much convincing Sharpe Ratios...

Anybody could share sweet or bitter experience about doing these stuff in R?

Any pointers to good packages?

Thanks a lot!
