occurrences

A harmonized, multi-source occurrence dataset containing cleaned
georeferenced records for three species:<ul>
<li>Araucaria angustifolia (Parana pine)</li>
<li>Cyanocorax caeruleus (Azure jay)</li>
<li>Handroanthus serratifolius (Yellow trumpet tree)</li>
</ul>Records were retrieved from GBIF, speciesLink, BIEN, and
iDigBio, standardized through the package workflow, merged, and
cleaned to remove duplicates.

datasets

Automatically flags common spatial errors in biological collection data using metadata and specialists' information. RuHere implements a workflow to manage occurrence data through six steps: dataset merging, metadata flagging, validation against expert-derived distribution maps, visualization of flagged records, and sampling bias exploration. It specifically integrates specialist-curated range information to identify geographic errors and introductions that often escape standard automated validation procedures. For details on the methodology, see: Trindade & Caron (2026) <doi:10.64898/2026.02.02.703373>.

occurrences function

A data frame where each row represents a georeferenced occurrence
record for one of the three species.
Columns correspond to the standardized output of
<code>format_columns()</code>, including:<ul>
<li><code>species</code>: Cleaned binomial species name</li>
<li><code>decimalLongitude</code>, <code>decimalLatitude</code>: Coordinates</li>
<li><code>year</code>: Year of collection/observation</li>
<li>Various taxonomic, temporal, locality, and metadata fields</li>
<li>Source identifiers added by <code>format_columns()</code> (e.g., <code>data_source</code>)</li>
</ul>
