vistributions 0.2.1

CRAN release: 2026-10-16

Bug Fixes

  • vdist_normal_plot() now properly scales the x-axis grid to span mean ± 4 * sd (BUG-01).
  • vdist_f_perc() adapts upper x-axis limit dynamically beyond 4.0 when quantiles exceed the default plotting range (BUG-02).
  • vdist_t_prob() handles negative percentile values (perc <= -5) without “wrong sign in ‘by’ argument” sequence error (BUG-03).
  • vdist_chisquare_plot() ensures shaded fill polygon coordinates match the full extent of xaxis_range (BUG-04).
  • Guarded theoretical standard deviation calculation for the F distribution against division-by-zero when denominator degrees of freedom is less than or equal to 4 (den_df <= 4) (BUG-05).
  • vdist_t_prob(type = "both") corrects color mapping and annotation placement so left/right shaded tails and central body match their respective regions (BUG-06).
  • check_positive() now strictly enforces positive values (val <= 0), rejecting zero and negative inputs (BUG-07).
  • check_suggests() formats informative error messages identifying the missing package prior to aborting execution (BUG-08).
  • vdist_binom_prob() validates numeric types for n, p, and s before performing range checks (BUG-09).
  • check_range() replaces bitwise | with logical || to eliminate scalar evaluation warnings in modern R (BUG-10).
  • Visual test snapshot names for vdist_t_prob() interval and both types are properly aligned (BUG-11).
  • Removed unprompted network polling (available.packages()) and interactive prompts during package startup in .onAttach(); retained rotating educational tips (BUG-12).
  • vdist_normal_perc() scales x-axis bounds dynamically with standard deviation (BUG-13).
  • vdist_binom_prob(type = "upper") strictly shades bars where x >= s (BUG-14).
  • vdist_binom_prob(type = "exact") matches success counts via integer equality rather than floating-point density comparison (BUG-15).
  • vdist_t_prob(type = "upper") aligns text annotation colors with polygon fill colors (BUG-16).
  • Added missing positive degrees of freedom validations across t, F, and chi-square functions (BUG-17).
  • F distribution normal approximation overlay is strictly clamped to non-negative support (x >= 0) (BUG-18).
  • vdist_binom_perc() allows percentile input tp across the full valid range (0, 1) rather than capping at 0.5 (BUG-19).

Documentation & Vignettes

  • Fixed pedagogical and numerical discrepancies in vignettes/introduction-to-vistributions.Rmd:
    • Corrected Normal 15th percentile problem cutoff (0.15 instead of 0.85).
    • Aligned Binomial sample size (n=12n = 12 consistently).
    • Synchronized Chi-square question text with lower-tail probability evaluation.
    • Aligned Student’s t 95% interval problem (0.95 instead of 0.8).
    • Fixed inversion of Student’s t interval vs both probability examples.
    • Standardized knitr chunk options (fig.align = 'center').
    • Corrected typographic errors.
  • Added explicit @return documentation across all exported plotting and calculation functions.
  • Added .github/CONTRIBUTING.md, issue templates, PR template, and upgraded CODE_OF_CONDUCT.md to Contributor Covenant v2.1.

Package Hygiene & Infrastructure

  • Removed stale SVG files in tests/figs/ and updated test suite to testthat 3rd edition (Config/testthat/edition: 3).
  • Bumped dependency requirement to R (>= 4.1.0).
  • Removed unused magrittr dependency from Imports:.
  • Configured automated pkgdown website deployment via Netlify.
