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.

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 Package is located at: URL: https://r-forge.r-project.org/projects/candlesticks/ Date/Publication: 2018-09-06 17:34:30 This R package is not in github or cran. I believe this package deal with Candlestick Pattern Recognition, similar TA-Lib’s Pattern Recognition.
