tikatuwq 0.8.2 (2026-01-16)

• CRAN maintenance: Patch release for CRAN compliance. Fixed example in plot_map() to use internal dataset wq_demo instead of external file reference. All examples and tests now comply with CRAN policies (no local file dependencies, write only to tempdir). No API changes.

tikatuwq 0.8.1

• Fix (CRAN compliance): render_report() now copies the template to a temporary directory before rendering to comply with CRAN filesystem policies. All intermediate files generated during rendering are written only to output_dir (default tempdir()), never to the package installation directory. Tests for render_report() are now skipped on CRAN (skip_on_cran()) and use withr::local_tempdir() for proper cleanup.

tikatuwq 0.8.0 (2025-11-17)

• Data and documentation update: The wq_demo example dataset is now a subset of real data (from BURANHEM river monitoring, 4 points, years 2020–2024, 20 rows). Includes extra columns: rio, lat, and lon.
• All examples and vignettes now use real, representative dataset (greater realism and reproducibility).
• Documentation (R/data_wq_demo.R, inst/extdata/wq_demo_README.txt, vignettes, README) updated to reflect the change.
• No API breakage; all functions and test expectations remain valid for the new dataset structure and size.

tikatuwq 0.7.3 (2025-10-31)

• Funções iet_carlson() e iet_lamparelli() agora aceitam data.frame com .keep_ids.
• Conversão automática de formato BR ("," / "<" / ">") e de p_total (mg/L) → tp (µg/L).
• iqa() mais robusto: alias temp para temperatura, numificação segura e reponderação com na_rm=TRUE.
• Campos identificadores (rio, ponto, data, lat, lon) agora são automaticamente reconhecidos e preservados via .keep_ids.

tikatuwq 0.7.2 (2025-10-22)

Changes in this version:

• Fixed incoming NOTE detected in pre-tests:
  • Removed non-standard fields (DOI, Citation) from DESCRIPTION.
  • Updated inst/CITATION to use the modern bibentry() format instead of the deprecated citEntry().
• Minor internal documentation updates (no API or functional changes).

tikatuwq 0.7.1

• Title field adjusted per CRAN request: now "Water Quality Assessment and Environmental Compliance in Brazil".
• Added Zenodo DOI and formal citation entry (citation("tikatuwq")).
• Updated README (EN/PT) with citation, DOI badge, and institutional context.
• No changes in functions or internal code.

tikatuwq 0.7.0

• New functions param_analysis() and param_analysis_multi():
  • Enable detailed analysis of specific parameters by point, river, or group of points.
  • Support cross-comparisons (multiple parameters at one point or multiple points for the same parameter).
  • Include simple temporal trend detection and basic statistical summary.
  • Return standardized data frames compatible with visualization and reporting tools.
• Automated tests for new modules (test-param_analysis.R, test-param_analysis_multi.R).
• Code updated to meet CRAN best practices (all checks passed 100% cleanly).
• Minor stability improvements in plot_trend() and plot_map() (controlled messages).

tikatuwq 0.6.2 (2025-10-07)

• Fix: resolved codoc WARNING for generate_analysis() (docs matched to code).
• No functional code changes.

tikatuwq 0.6.1

• Maintenance update requested by CRAN.
• Fixed relative link README-pt.md, now using absolute HTTPS URL.
• No functional changes in code.

tikatuwq 0.6.0

• New function plot_trend():
  • Visualize time series for parameters (e.g., turbidity, OD, IQA).
  • Add trend lines by group/point using three methods:
    • Theil–Sen (robust to outliers),
    • OLS (ordinary least squares),
    • LOESS (smoothed curve).
  • Supports faceting by river/point and customizable number of samples.
  • Returns a ggplot object ready for plotting.
• Updated documentation for plot_trend() with practical examples.
• Updated pkgdown site with dedicated section for trend visualization.

tikatuwq 0.5.1 (2025-10-01)

• Fix: replaced broken URLs in help pages.

tikatuwq 0.5.0

• New: plot_map() — interactive map of sampling points using Leaflet (optional dependency via Suggests).
• Examples wrapped in if (interactive()) / \donttest{} to avoid network calls on CRAN.
• Tests: added skip_on_cran() and skip_if_not_installed("leaflet") guards for map tests.
• Encoding hardening: replaced non-ASCII characters with \u escapes.
• Dependencies: removed unused htmltools from Imports.
• Docs: roxygen updates; added function to “Visualizations” reference.
• No breaking changes; existing public API unchanged.

tikatuwq 0.4.6 (2025-09-22)

• DESCRIPTION rewritten in English-only to avoid CRAN “Possibly misspelled words” NOTE.
• Fixed DESCRIPTION URLs (Lamparelli 2004, CONAMA 357/2005).
• Updated spell-check list (inst/WORDLIST).
• Added expanded acronyms and DOIs/URLs in DESCRIPTION.
• Documented @return for all exported functions.
• Maintained MIT license text (per CRAN policy).
• Minor internal refactor: conama_limits() now accepts class argument for filtering.
