rPref 1.0 – Computing Pareto Optima and Database Preferences

April 28, 2016

This is a re-post from the R packages mailing list

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.

Comments and contributions are very welcome via github:

Best regards,

Patrick Roocks
