+
+== DESCRIPTION:
+
+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.
+
+
+== FEATURES/PROBLEMS:
+
+* Pure Ruby. Works on Ruby 1.8.7, 1.9 and JRuby 1.4
+* Slower than RSRuby, but more robuts
+
+== SYNOPSIS:
+Below is a simple example of RinRuby usage for simple linear regression. The simulation parameters are defined in Ruby, computations are performed in R, and Ruby reports the results. In a more elaborate application, the simulation parameter might come from input from a graphical user interface, the statistical analysis might be more involved, and the results might be an HTML page or PDF report. 
+
+<b>Code</b>:
+
+      require "rinruby"
+      n = 10
+      beta_0 = 1
+      beta_1 = 0.25
+      alpha = 0.05
+      seed = 23423
+      R.x = (1..n).entries
+      R.eval <<EOF
+          set.seed({seed})
+          y <- {beta_0} + {beta_1}*x + rnorm({n})
+          fit <- lm( y ~ x )
+          est <- round(coef(fit),3)
+          pvalue <- summary(fit)$coefficients[2,4]
+      EOF
+      puts "E(y|x) ~= {R.est[0]} + {R.est[1]} * x"
+      if R.pvalue < alpha
+        puts "Reject the null hypothesis and conclude that x and y are related."
+      else
+        puts "There is insufficient evidence to conclude that x and y are related."
+      end
+
+<b>Output</b>:
+
+      E(y|x) ~= 1.264 + 0.273 * x
+      Reject the null hypothesis and conclude that x and y are related.
+

+
+* R
