Examples

if (FALSE) { # \dontrun{
# Assuming 'topics_over_time_model' is a BERTopic model object
visualize_topics_over_time(model = topic_model,
                           topics_over_time_model = topics_over_time,
                           top_n_topics = 5,
                           filename = "plot")
