This follows from the same goals as cpp11:

You can install the development version of cpp11armadillo like so:



I have provided a package template for RStudio that also works with VS Code.

The idea of this package is to be naive and simple (like me).

From RStudio/VSCode create a new project and run:


Then follow the instructions from the README.

The vignettes contains detailed examples that I use to test cpp11armadillo, these include Ordinary Least Squares, Leontief inverse, eigenvalues, and the Capital Asset Pricing Model (CAPM).
