rcppmlpackexamples: Example of using mlpack via its C++ API from R

About

mlpack has supported header-only compilation since the 4.0.0 release. It also contains an R package that has been part of CRAN for years. Its focus is on access from R at the R prompt: underlying mlpack functions are properly wrapped.

Sometimes, however, we would like to access the C++ API of mlpack 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

For now the package is available only at GitHub so please rely on remotes::install_github():

> remotes::install_github("eddelbuettel/rcppmlpack-examples")

Miscellaneous

We use the rcpp prefix to not conflate this repo with the existing mlpack examples repo.
