PhytoIn 0.2.1

• AGB() examples use a single data.table thread (data.table is used internally by 'BIOMASS'), so that CPU time does not exceed elapsed time during checks.
• Removed the dependency on 'ggforce'. BAplot() now draws the basal-area circles as polygons with ggplot2::geom_polygon(); circle positions are still arranged with 'packcircles', so maps are unchanged.
• AGB(): the default of correct.taxon is now FALSE, so AGB() does not access the internet unless requested. Use correct.taxon = TRUE to standardize taxon names with the online TNRS service (previous default).
• AGB(): taxon standardization via the online TNRS service (correct.taxon = TRUE) now fails gracefully. If the service cannot be reached, a warning is issued and the taxon names are used as provided, instead of stopping with an error.
• AGB(): the optional cache directory no longer falls back to the user's home directory (R < 4.0.0 now uses the session tempdir()); the cache is created only on request (cache = TRUE or NULL).
• AGB(): examples that run during checks no longer require an internet connection (correct.taxon = FALSE); the online example is wrapped in \dontrun{}.
• Documentation of correct.taxon and cache clarified.

• Initial internal version.
• Prototypes of the core functions for phytosociological analysis.
• Not submitted to CRAN.

PhytoIn 0.2.0 (2025-10-01)

• New function summary.param() (S3) with concise and robust output.
• collector.curve() and rarefaction() now include confidence intervals (ribbons) and configurable themes.
• AGB() no longer depends on rappdirs; optional cache via tools::R_user_dir() and BIOMASS::createCache().
• BAplot() fixed (global bindings) and compatible with rectangular plots and individual coordinates.
• New datasets: quadrat2_plot.df, quadrat2_tree.df, quadrat3_rect.df.
• Documentation, examples, and NAMESPACE/DESCRIPTION revised.

First public release on CRAN

• phytoparam(), summary.param(), plot.param() for phytosociological parameters and diversity indices.
• AGB() for aboveground biomass, carbon, and CO₂ equivalent (wrapper of BIOMASS).
• stratvol() for stratified volume by DBH classes.
• collector.curve() for species accumulation curves.
• rarefaction() for individual-based rarefaction with confidence intervals.
• BAplot() for visualization of basal areas (rectangular plots and individual coordinates).
• Included datasets: quadrat.df, point.df, quadrat2_plot.df, quadrat2_tree.df, quadrat3_rect.df.
