Sound Waves Onto Morphometric Data
Implement a promising, and yet little explored protocol for bioacoustical analysis, the eigensound method by MacLeod, Krieger and Jones (2013)
Spider Knowledge Online
Allows the user to connect with the World Spider Catalogue (WSC; < https://wsc.nmbe.ch/>) and the World Spider Trait (WST; < https://spidertraits.sci.muni.cz/>) databases. Also performs several basic functions such as checking names validity, retrieving coordinate data from the Global Biodiversity Information Facility (GBIF; < https://www.gbif.org/>), and mapping.
Spatial Interpolation of Genetic Data
The spatial interpolation of genetic distances between samples is based on a modified kriging method that accepts a genetic distance matrix and generates a map of probability of lineage presence. This package also offers tools to generate a map of potential contact zones between groups with user-defined thresholds in the tree to account for old and recent divergence. Additionally, it has functions for IDW interpolation using genetic data and midpoints.
An Interface to IMF (International Monetary Fund) Data
Provides low-level access to the International Monetary Fund Statistical Data and Metadata eXchange ('SDMX') 3.0 API, available at < https://data.imf.org/>, and a concise workflow for discovering datasets, inspecting dimensions, and downloading observations as tidy data frames.
Create and Emit 'OpenLineage' Events
Construct and validate run events that follow the 'OpenLineage' specification < https://openlineage.io/>. Model run lifecycles, datasets, and extensible facets with protocol-aware 'R' objects. Serialize events into deterministic JavaScript Object Notation (JSON) while preserving wire field names. Deliver events synchronously over Hypertext Transfer Protocol (HTTP) with authentication and retries, or use offline transports for local development and testing.
Bayesian LDA for Mixed-Membership Clustering Analysis
Estimates the Bayesian LDA model for mixed-membership clustering based on different types of data
(i.e., Multinomial, Bernoulli, and Binomial entries). Albuquerque, Valle and Li (2019)
Query 'Azure Data Lake Storage Gen2' with 'DuckDB'
Provides convenience utilities for using 'DuckDB' directly over datasets stored in 'Azure Data Lake Storage Gen2' (ADLS Gen2, 'abfss://'). Opens connections configured for Azure-backed 'Delta Lake' and 'Parquet' data, registers Azure credentials as 'DuckDB' secrets, and supports optional repository mirrors for restricted networks. Integrates well with 'DBI' for SQL workflows and with 'dplyr' and 'dbplyr' for lazy table queries.
Calculate the NLTT Statistic
Provides functions to calculate the normalised Lineage-Through- Time (nLTT) statistic, given two phylogenetic trees. The nLTT statistic measures the difference between two Lineage-Through-Time curves, where each curve is normalised both in time and in number of lineages.
Extended Joint Models for Longitudinal and Time-to-Event Data
Fit joint models for longitudinal and time-to-event data under the Bayesian approach. Multiple longitudinal outcomes of mixed type (continuous/categorical) and multiple event times (competing risks and multi-state processes) are accommodated. Rizopoulos (2012, ISBN:9781439872864).
Probabilistic Support Vector Machines
Implements kernel-based classification Support Vector Machines with reliable estimated probabilities of class membership. Theoretical support for the functions in this package can be found in Duarte Silva (2025)
