About
mlpack has supported header-onlycompilation since the 4.0.0 release. It also containsan R package thathas been part ofCRAN foryears. Its focus is on access from R at the R prompt: underlyingmlpack functions are properlywrapped.
Sometimes, however, we would like to access the C++ API ofmlpack from the C++ side of an R package.This package provides a working demonstration of how to do this.
Scope
Currently, the package contains two examples covering
- linear regression (with optional regularization)
- random forest classification of a multinomial response
- loan default prediction using a decision tree
Installation
The package is on CRAN and can be installed via the usual
>install.packages("rcppmlpackexamples")Ther-univerepage has source and binary builds from the repository version whichmay differ from the CRAN version and shows how to install them. Lastly,one can always rely onremotes::install_github():
> remotes::install_github("eddelbuettel/rcppmlpack-examples")Miscellaneous
We use thercpp prefix to not conflate this repo withthe existingmlpackexamples repo.
