Learn R Programming

⚠️There's a newer version (2.6.2) of this package.Take me there.

LibOPF-in-R

This is a version in R language of an famous brazilian classifier called LibOPF (https://github.com/jppbsi/LibOPF), which is a library of functions and programs for free usage in the design of optimum-path forest classifiers.

Please read the package help and visit the Wiki for all the information needed to work with LibOPF: https://github.com/jppbsi/LibOPF/wiki, http://www.ic.unicamp.br/~afalcao/libopf/
