[ANN] New daru released with a ton of new features.

Hello,

I've just release daru version 0.0.5, with a ton of new features for data analysis.

To summarize, the new features are as follows:

• New improved plotting DSL
• Faster CSV loading
• Compatibility with nmatrix and statsample
• Ability to split or group data with the #group_by function
• Generating quick data statistics with #pivot_table
• A whole array of statistics functions on Daru::DataFrame
• Hierarchical indexing of data with Daru::MultiIndex
• Bugfixes

Check out the gem at rubygems(https://rubygems.org/gems/daru) and also read the accompanying blog post to get further information: http://v0dro.github.io/blog/2015/02/24/data-analysis-in-ruby-part-2/

Over and above this, I have a few things in mind for the next release of daru. Some of the key features are:

• Complete compatibility with statsample for performing various statistics operations.

• Read data into DataFrame from more sources (currently only CSV support is active)

• Support for indexing data on TimeSeries.

• Arel-like querying syntax for DataFrame.

If you folks have any suggestions apart from those listed above, please let me know. It would be great feedback!

Regards,
