The main purpose of the FSelectorRcpp package is the feature selection based on the entropy function. However, it also contains a function to discretize continuous variable into nominal attributes, and we decided to slightly change the API related to this functionality, to make it more user-friendly. EDIT: Updated version (0.2.1) is on CRAN. It can be installed using: install.packages("FSelectorRcpp") The dev version can be installed using devtools: devtools::install_github("mi2-warsaw/FSelectorRcpp", ref = "dev")
