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.
