Efficient Outlier Detection for Large Time Series Databases

Programs for detecting and cleaning outliers in single time series and in time series from homogeneous and heterogeneous databases using an Orthogonal Greedy Algorithm (OGA) for saturated linear regression models. The programs implement the procedures presented in the paper entitled "Efficient Outlier Detection for Large Time Series Databases" by Pedro Galeano, Daniel Peña and Ruey S. Tsay (2026), working paper, Universidad Carlos III de Madrid. Version 1.1.2 fixes one bug.

Selecting Variable Subsets

A collection of functions which (i) assess the quality of variable subsets as surrogates for a full data set, in either an exploratory data analysis or in the context of a multivariate linear model, and (ii) search for subsets which are optimal under various criteria. Theoretical support for the heuristic search methods and exploratory data analysis criteria is in Cadima, Cerdeira, Minhoto (2003, ). Theoretical support for the leap and bounds algorithm and the criteria for the general multivariate linear model is in Duarte Silva (2001, ). There is a package vignette "subselect", which includes additional references.

Robust Selection Algorithm

An implementation of algorithms for estimation of the graphical lasso regularization parameter described in Pedro Cisneros-Velarde, Alexander Petersen and Sang-Yun Oh (2020) < http://proceedings.mlr.press/v108/cisneros20a.html>.

Aggregate Multiple ROC Curves into One Global ROC

Aggregates multiple Receiver Operating Characteristic (ROC) curves obtained from different sources into one global ROC. Additionally, it’s also possible to calculate the aggregated precision-recall (PR) curve.

Helper Functions for Species Delimitation Analysis

Helpers functions to process, analyse, and visualize the output of single locus species delimitation methods. For full functionality, please install suggested software at < https://legallab.github.io/delimtools/articles/install.html>.

Credential Chain for Seamless 'OAuth 2.0' Authentication to 'Azure Services'

Implements a credential chain for 'Azure OAuth 2.0' authentication based on the package 'httr2''s 'OAuth' framework. Sequentially attempts authentication methods until one succeeds. During development allows interactive browser-based flows ('Device Code' and 'Auth Code' flows) and non-interactive flow ('Client Secret') in batch mode.

Progressive Web App Support for Shiny

Adds Progressive Web App support for Shiny apps, including desktop and mobile installations.

Find Hex Logos for CRAN Packages

Scavenge the web for possible hex logos for CRAN packages.

CSS Layouts (Grid and Flexbox) Implementation for R/Shiny

Allows easy creation of CSS layouts (grid and flexbox) directly from R without added CSS.

ARAchnid 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.
