fuzzystring - Fast Fuzzy String Joins for Data Frames

Perform fuzzy joins on data frames using approximate string matching. Implements inner, left, right, full, semi, and anti joins with string distance metrics from the 'stringdist' package, including Optimal String Alignment, Levenshtein, Damerau-Levenshtein, Jaro-Winkler, q-gram, cosine, Jaccard, and Soundex. Uses a 'data.table' backend plus compiled 'C++' result assembly to reduce overhead in large joins, while adaptive candidate planning avoids unnecessary distance evaluations in single-column string joins. Suitable for reconciling misspellings, inconsistent labels, and other near-match identifiers while optionally returning the computed distance for each match. Bibliographic references include Van der Loo, M. P. J. (2014) <https://CRAN.R-project.org/package=stringdist> and Robinson, D. (2015) <https://github.com/dgrtwo/fuzzyjoin>.

ppendemic - A Glimpse at the Diversity of Peru's Endemic Plants

Provides an updated database of accepted endemic plant taxa from Peru. The current collection contains over 8,000 taxonomic records at species and infraspecific ranks. Data are derived from Govaerts, R., Nic Lughadha, E., Black, N. et al., 'The World Checklist of Vascular Plants: A continuously updated resource for exploring global plant diversity', published in Sci Data 8, 215 (2021) <doi:10.1038/s41597-021-00997-6>.

wcvpmatch - Taxonomic Name Reconciliation Against the 'WCVP' Backbone

Standardizes and reconciles scientific plant names against a World Checklist of Vascular Plants ('WCVP')-style taxonomic backbone. The package parses names into taxonomic components and applies staged exact and fuzzy matching for binomial and trinomial inputs, including infraspecific rank-aware checks. It also returns accepted-name context and row-level matching flags to support reproducible, auditable preprocessing for downstream biodiversity, spatial, and trait analyses. A user-supplied backbone can be passed through 'target_df'; when the optional companion package 'wcvpdata' is installed, its default checklist can also be used.

perumammals - Taxonomic Backbone and Name Validation Tools for Mammals of Peru

Provides a curated taxonomic backbone of mammal species from Peru based on Pacheco et al. (2021) "Lista actualizada de la diversidad de los mamíferos del Perú y una propuesta para su actualización" <doi:10.15381/rpb.v28i4.21019>. The package includes standardized species data, occurrence by ecoregions, endemism status, and tools for validating and matching scientific names through exact and fuzzy procedures. It is designed as a lightweight and dependable reference for ecological, environmental, biogeographic, and conservation workflows that require reliable species information for Peruvian mammals.

peruflorads43 - Check Threatened Plant Species Status Against Peru's Supreme Decree 043-2006-AG

Provides tools to match plant species names against the official threatened species list of Peru (Supreme Decree 043-2006-AG, 2006). Implements a hierarchical matching pipeline with exact, fuzzy, and suffix matching algorithms to handle naming variations and taxonomic changes. Supports both the original 2006 nomenclature and updated taxonomic names, allowing users to check protection status regardless of nomenclatural changes since the decree's publication. Threat categories follow International Union for Conservation of Nature standards (Critically Endangered, Endangered, Vulnerable, Near Threatened).

rsdot - Programmatic Access to Spatial Data from 'SDOT-PCM' Peru

Provides programmatic access to official geographic information from the Secretariat of Demarcation and Territorial Organization ('SDOT') of the Presidency of the Council of Ministers ('PCM') of Peru. Facilitates the download, reading, and manipulation in 'R' of vector layers on geographic modeling, National Institute of Statistics and Informatics ('INEI') census limits, population centers, infrastructure, risks, and hazards. IMPORTANT: 'INEI' census limit information is referential and does not constitute official territorial limits nor has legal demarcatory effect.

tidyttmoment - Functional Trait Moment Calculation

Calculates the community four 'moments' (mean, variance, skewness, and kurtosis) of a given trait based on the moments described in Wieczynski et al. (2019) <doi:10.1073/pnas.1813723116>. These functional metrics are extremely useful in characterizing the distribution of traits in a plant community. It also provides tidyverse-friendly wrappers to seamlessly calculate advanced functional diversity indices (e.g., FDis, Rao's Q) using 'fundiversity' (Grenie et al. 2023 <doi:10.1111/ecog.06585>) and functional rarity indices using 'funrar' (Grenie et al. 2017 <doi:10.1111/ddi.12629>). Evaluating these community-weighted moments and diversity metrics allows researchers to evaluate shifts in optimal phenotypes and understand ecological filtering with exactness.
