## Details

This package uses the reticulate package to make an interface with the Altair Python package. To promote consistency in usage of reticulate among different R packages, it is recommended to use a common Python environment, called "r-reticulate".

Depending on your setup, you can create this environment using reticulate::conda_create() or reticulate::virtualenv_create(), as described in this reticulate article, or in this package's Installation article.
