#=RinRuby: Accessing the R[http://www.r-project.org] interpreter from pure Ruby
#
#RinRuby is a Ruby library that integrates the R interpreter in Ruby, making R's statistical routines and graphics available within Ruby.  The library consists of a single Ruby script that is simple to install and does not require any special compilation or installation of R.  Since the library is 100% pure Ruby, it works on a variety of operating systems, Ruby implementations, and versions of R.  RinRuby's methods are simple, making for readable code.  The {website [rinruby.ddahl.org]}[http://rinruby.ddahl.org] describes RinRuby usage, provides comprehensive documentation, gives several examples, and discusses RinRuby's implementation.
