# How to use cpp11armadillo?

## Read the documentation

The [package website](https://cpp4r.org) covers the basics, customization, and
advanced usage of the package.

## Test the package

1. Open `./dev/01_load_or_install.R` and run it.
2. Open `./src/01_ols.cpp`, inspect the OLS functions.
3. Create your own functions in `./02_your_functions.cpp`.
4. Run `devtools::load_all()` before testing your functions, and then add tests
   to `./dev/02_test.R` and run it.
5. Run `./dev/03_readme_and_license.R` to add a README and license.
6. Run `devtools::install()` in `./dev/01_load_or_install.R` to install the
   package locally when you are ready.
7. The package template includes a configuration with a predefined number of
   cores to use. You can change this value by doing this:

   Unix: Edit `./src/Makevars.in` to set `DARMA_OPENMP_THREADS` to another
         value or edit `./configure` to change `PKG_NCORES` to another value.
   
   Windows: Edit `./src/Makevars.win` to set `DARMA_OPENMP_THREADS` to another
            value.
