sshist 0.1.3 (2026-03-04)

Algorithm Improvements

• Updated the binning resolution limit formula to N_max = Range / (2 * Min_Resolution) to prevent the "comb effect" (sampling artifacts). This change aligns the R implementation with the author's reference code.
• The n_max parameter in sshist() is now strictly bounded by the resolution limit to prevent overfitting.

Documentation

• Fixed formatting in the DESCRIPTION file.
• Updated the faithful dataset examples in README.md to reflect the corrected optimal bin calculations (N changed from 37 to 21).
• Added CRAN download badges to README.md.
• Expanded reference links in README.md to include the original toolboxes and GitHub repositories from the algorithm's authors.

sshist 0.1.2 (2026-02-13)

CRAN Submission Fixes

• Fixed DESCRIPTION file reference formatting:

  • Added author names (Shimazaki and Shinomoto) to citation

• Improved documentation:

  • Added \value tags to all exported S3 method documentation files
  • Added comprehensive descriptions of return values and side effects for plot and print methods
  • Updated print methods to return objects invisibly following R best practices
  • Clear old images

• Fixed vignette:

  • Corrected graphical parameter handling in introduction.Rmd
  • Now properly stores and restores user's par() settings

Internal Changes

• Added invisible(x) return statements to print.sshist() and print.sshist_2d() methods
