Changelog

bertopicr 0.3.6

• Documentation & Vignette fixes and bump version to 0.3.6

bertopicr 0.3.5

• Added setup_python_environment() helper for reticulate setup.
• Added train_bertopic_model() helper for end-to-end model training.
• Added save_bertopic_model() and load_bertopic_model() to persist and reload models with extras.
• Added vignettes train_and_save_model.Rmd and load_and_reuse_model.Rmd.
• Added demo script inst/scripts/train_model_function_demo.R.

bertopicr 0.3.4

• The visualize_documents_2d() function with richer labeling options was added to the already existing ones for document visualization (visualize_documents() and visualize_documents_3d()).
• The visualize_documents_3d() function also includes improved labeling options than in previous versions.

bertopicr 0.3.3

• The update of the Python package BERTopic to version 0.17.4 and its dependencies introduced conflicts with certain R packages. Avoid attaching R libraries like arrow or plotly to the workflow.
• Due to the update of the Python package BERTopic and its dependencies, it is recommended to load the Python packages BERTopic and sentence-transformers before certain R libraries, e.g., readr_rds().
• The README.md file was rewritten for easier understanding of the installation options and requirements.
• A vignette was added (alongside the Quarto tutorial and the pre-computed HTML file).
• Setup of a pkgdown website on Github (https://tpetric7.github.io/bertopicr) and another website on Netlify (https://bertopicr.netlify.app/).

bertopicr 0.3.2

• If you update the Python package BERTopic to version 0.17.0, you might have to update other packages as well or (like myself) to create a new virtual environment with compatible packages.
• After updating to BERTopic=0.17.0, you might experience that the visualize_documents() function doesn’t render the dots in the scatterplot. A simple temporary fix is to open the Python file _documents.py of the visualize_documents() function ofBERTopic (on my Windows system it sits in anaconda3\envs\bertopic\Lib\site-packages\bertopic\plotting\) and change go.Scattergl to go.Scatter in the fig.add_trace() function (it occurs twice in the Python script).

bertopicr 0.3.1

• Added .onload() function to allow MacOS users to import BERTopic and other installed Python modules from the virtual environment.

bertopicr 0.3.0

• The R package bertopicr introduces training and visualization helpers to reproduce functions of the Python BERTopic package. For easier memorization, the functions names are (nearly) identical to those of the Python package BERTopic.

bertopicr 0.2

• A preliminary collection of R wrapping functions of the Python BERTopic package and a tutorial for R users.
