[R] [R-pkgs] rPref 1.0 - Computing Pareto Optima and Database Preferences

Dear R users,
the first 1.0 version of the rPref package is now on CRAN.
rPref allows to select the Pareto-optimal tuples from a data set, also
called Skylines in the database community. For example, optimal tuples
from mtcars according to "high(mpg) * high(hp)" (where "*" is the Pareto
operator) are those cars, for which no other dominating car exists.
There, a car dominates another car if its horsepower or miles-per-gallon
value is strictly better while the other value is better or equal.
See http://p-roocks.de/rpref/index.php?section=examples for more examples.
The changes of this version include:
- A new function get_btg_dot to generate Better-Than-Graphs induced by
the preference using Graphviz.
- Fixed compatibility issues with new versions of dplyr and testthat.
