Fix negative RPD values (Fixed by @j-mezger).
Renamed parallel_coord2() to plot_configurations(). Completely rewrite parallel_coord() and plot_configurations() to produce nicer tickmarks and fix many bugs.
New functions parameters_tree(), parameters_summarise(), irace_summarise().
plot_experiments_matrix() now shows rejected configurations with a red X.
Give a better error if pandoc is missing.
New function ablation_plot() to plot the result of irace::ablation().
New function summarise_by_configuration().
Implement all plots that were available in the irace package and a few more.
First version in CRAN.
