bertopic_topics_over_time

Wrapper for Python <code>BERTopic.topics_over_time()</code>. Returns a tibble and
attaches the original Python dataframe in the <code>"_py"</code> attribute for use in
visualization.

Interface to the Python package 'BERTopic' <https://maartengr.github.io/BERTopic/index.html> for transformer-based topic modeling. Provides R wrappers to fit BERTopic models, transform new documents, update and reduce topics, extract topic- and document-level information, and generate interactive visualizations. 'Python' backends and dependencies are managed via the 'reticulate' package.
