TTR Pattern Recognition functions??

[quantintell]

First thanks for providing TTR to R community for technical trading analysis and trading rules with R.
TA-Lib is widely used by trading software requiring to perform technical analysis of financial market data open-source API for C/C++, Java, Perl, Python and .NET.
TTR provides most TA-Lib indicators or functions, except the Pattern Recognition categories.
Here are just a few pattern recognition functions TA-Lib provides to its users.
CDL2CROWS Two Crows
CDL3BLACKCROWS Three Black Crows
CDL3INSIDE Three Inside Up/Down
CDL3LINESTRIKE Three-Line Strike
CDL3OUTSIDE Three Outside Up/Down
CDL3STARSINSOUTH Three Stars In The South
CDL3WHITESOLDIERS Three Advancing White Soldiers
CDLABANDONEDBABY Abandoned Baby
CDLADVANCEBLOCK Advance Block
My questions are three

1. I know currently TTR does not provide the Pattern Recognition categories in the package, Has TTR plan to have pattern recognition in the near future?

2. Do you know any other R package provides this similar pattern recognition functions in R quantitate finance area?

3. Or R have interface to TA-Lib C++, so we can use TA-Lib through R.

R has a Package: candlesticks. This package deals with Candlestick Pattern Recognition.
Description: Filter Japanese Candlestick Patterns like Doji, Engulfing, Harami, etc. out of OHLC price data.
Author: Andreas Voellenklee

This R package is not in github or cran.
I believe this package deal with Candlestick Pattern Recognition, similar TA-Lib’s Pattern Recognition.
