Statisticus

Statisticus aims to do three things well:

• Integrate other workflow tools to statistical analysis: memoization, composition, concurrency, and distributed computing
• Remove seams from the R runtime and the R bindings (RSRuby)
• Bridge simple Ruby-centric data containers (hashes, 2-dimensional arrays) into R-centric data containers (lists and data frames)

Usage

The most basic usage can be:

  stats_class :geometric_mean

This will:

# create a class, GeometricMean # look for geometric_mean.r somewhere in this gem, in the working directory where the Ruby process is started, or in the ~/.statisticus directory # expect geometric_mean to be a defined function in geometric_mean.r

If that holds true, then you’ve got the easiest access to the R runtime I can think of.

Since I’m using TeguGears here, I have a few other tricks baked in:

• The calls are memoized. So, GeometricMean.call([1,2,3]) gets stored in a central repository which can be balanced, pruned, and managed if you’d like.
• The calls can be composed, so things like (SquareRoot | GeometricMean ).call([1,2,3]) will work.
• Other features are on their way, just not all tested, like concurrency and distributed processing.

A more interesting example might be:

  class Whatever
    # Fill in the gaps here.
  end

Decide if I want to move my standard stats libs over here. Possibly all of Sirb as well?

Put all of these into Panorama
