This package provides tools to fit and compare Ornstein-Uhlenbeck models for evolution along a phylogenetic tree.

This package provides tools for the computation of the matrix exponential, logarithm, square root, and related quantities.

Assemble the panels of computerized adaptive multistage testing by the bottom-up and the top-down approach, and simulate the administration of the assembled panels. The full documentation and tutorials are at <https://github.com/xluo11/Rmst>. Reference: Luo and Kim (2018) <doi:10.1111/jedm.12174>.

This package provides estimation and inference procedures for boundary regression discontinuity (RD) designs using local polynomial methods, based on either bivariate coordinates or distance-based approaches. Methods are developed in Cattaneo, Titiunik, and Yu (2025) <https://mdcattaneo.github.io/papers/Cattaneo-Titiunik-Yu_2025_BoundaryRD.pdf>.

This package provides a flexible alternative to the built-in rank() function called smartrank(). Optionally rank categorical variables by frequency (instead of in alphabetical order), and control whether ranking is based on descending/ascending order. smartrank() is suitable for both numerical and categorical data.

Suite of tools for using D3', a library for producing dynamic, interactive data visualizations. Supports translating objects into D3 friendly data structures, rendering D3 scripts, publishing D3 visualizations, incorporating D3 in R Markdown, creating interactive D3 applications with Shiny, and distributing D3 based htmlwidgets in R packages.

An interface to the Open Tree of Life API to retrieve phylogenetic trees, information about studies used to assemble the synthetic tree, and utilities to match taxonomic names to Open Tree identifiers'. The Open Tree of Life aims at assembling a comprehensive phylogenetic tree for all named species.

Utilities to access Integrated Food Security Phase Classification (IPC) and Cadre Harmonisé (CH) food security data. Wrapper functions are available for all of the IPC-CH Public API (<https://docs.api.ipcinfo.org>) simplified and advanced endpoints to easily download the data in a clean and tidy format.

Plots the Receiver Operating Characteristics Surface for high-throughput class-skewed data, calculates the Volume under the Surface (VUS) and the FDR-Controlled Area Under the Curve (FCAUC), and conducts tests to compare two ROC surfaces. Computes eROC curve and the corresponding AUC for imperfect reference standard.

This package provides a dependency management toolkit for R. Using renv, you can create and manage project-local R libraries, save the state of these libraries to a lockfile, and later restore your library as required. Together, these tools can help make your projects more isolated, portable, and reproducible.

From a given data frame, this package learns its Bayesian network structure based on a selected score.

Fast Bayesian estimation and forecasting of age-specific rates, probabilities, and means, based on Template Model Builder'.

Get programmatic access to the open data provided by the Czech Statistical Office (CZSO, <https://czso.cz>).

Exploratory principal component analysis for large-scale dataset, including sparse principal component analysis and sparse matrix approximation.

Structural handling of Finnish identity codes (natural persons and organizations); extract information, check ID validity and diagnostics.

This package provides a set of functions that allow stationary analysis and locally stationary time series analysis.

Three main functions about analyzing massive data (missing observations are allowed) considered from multiple layers of categories.

Estimation of party/candidate ideological positions that correspond to a Nash equilibrium along a one-dimensional space.

Allows you to easily execute expensive compute operations only once, and save the resulting object to disk.

Allows objects to be stored on disc and automatically recalled into memory, as required, by delayed assignment.

Data sets and code blocks for the book Statistical Analysis of Network Data with R, 2nd Edition'.

This package provides rolling statistical functions based on date and time windows instead of n-lagged observations.

XML package for creating and reading and manipulating XML', with an object model based on Reference Classes'.

Provide R functions to read/write/format Excel 2007 and Excel 97/2000/XP/2003 file formats.
