Empirical Transition Matrix
The etm (empirical transition matrix) package permits to estimate the matrix of transition probabilities for any time-inhomogeneous multi-state model with finite state space using the Aalen-Johansen estimator. Functions for data preparation and for displaying are also included (Allignol et al., 2011
Categorical Marginal Models
Quite extensive package for maximum likelihood estimation and
weighted least squares estimation of categorical marginal models (CMMs;

Interactive 3D Visualization of Molecular Structures
Provides an 'htmlwidgets' < https://www.htmlwidgets.org/> interface to 'NGL.js' < http://nglviewer.org/ngl/api/>. 'NGLvieweR' can be used to visualize and interact with protein databank ('PDB') and structural files in R and Shiny applications. It includes a set of API functions to manipulate the viewer after creation in Shiny.
Working with ISO8601 Dates and Times
Functions to parse strings with ISO8601 dates, times, and date-times into R-objects. Additionally, there are functions to determine the type of ISO8601 string and to standardise ISO8601 strings.
Working with Code Lists
Functions for working with code lists and vectors with codes. These are an alternative for factor that keep track of both the codes and labels. Methods allow for transforming between codes and labels. Also supports hierarchical code lists.
Creating and Reading Data Packages
Open, read data from and modify Data Packages. Data Packages are an open standard for bundling and describing data sets (< https://datapackage.org>). When data is read from a Data Package care is taken to convert the data as much a possible to R appropriate data types. The package can be extended with plugins for additional data types.
Curved Text in 'ggplot2'
A 'ggplot2' extension that allows text to follow curved paths. Curved text makes it easier to directly label paths or neatly annotate in polar co-ordinates.
Football Match Data of European Leagues
Contains match results from seven European men's football leagues, namely Premier League (England), Ligue 1 (France), Bundesliga (Germany), Serie A (Italy), Primera Division (Spain), Eredivisie (The Netherlands), Super Lig (Turkey). Includes Seasons 2010/2011 until 2019/2020 and a set of interesting covariates. Can be used all purposes.
Group-Adaptive Elastic Net Penalised Generalised Linear Models
Fit linear and logistic regression models penalised with group-adaptive elastic net penalties.
The group penalties correspond to groups of covariates defined by a co-data group set.
The method accommodates inclusion of unpenalised covariates and overlapping groups.
See Van Nee et al. (2021)
Conducts Mokken Scale Analysis
Contains functions for performing Mokken scale analysis on test and questionnaire data. It includes an automated item selection algorithm, and various checks of model assumptions.
