oeis.tools 0.3.1

Breaking changes

• create_bfile() no longer writes to the working directory by default: output_path must now be supplied.

Bug fixes and improvements

• New oeis_available() reports whether the OEIS web service can be reached (it may refuse requests from some cloud and CI hosts).
• get_graph_image() failed whenever ‘IRdisplay’ was installed (it passed an argument display_png() does not accept). It now calls display_png() correctly, and only inside a Jupyter kernel.
• HTTP requests now identify themselves with an oeis.tools User-Agent instead of a browser User-Agent string. (The 0.3.0 NEWS incorrectly said this was already the case.)
• Network and HTTP failures now raise an informative error naming the URL, and Sequence() reports a clear error when no OEIS entry exists.

Documentation

• Every exported function now has examples; examples that need the internet run only when oeis_available() is TRUE.
• Documented the return value of plot.Sequence().
• New package title and description.

oeis.tools 0.3.0

New features

• Sequence gains get_bibtex(), get_data_values(), get_graph_image(), get_graph_png() and get_keyword_description().
• BFile gains get_bfile_indices(); new create_bfile() helper.
• plot_data() supports overlaying several b-files on one plot (p argument) and returning the plot object (return_plot).

Documentation

• New “Getting started” vignette and expanded README.
• Public API now mirrors the Python oeis-tools package.
• Added citation information (citation("oeis.tools") and CITATION.cff).

Internal

• Expanded test suite; package passes R CMD check --as-cran.

oeis.tools 0.2.0

• Initial release: Sequence and BFile S3 classes, OEIS metadata and b-file fetching, gmp::bigz term storage, and ggplot2 plotting.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
