exams.forge - Support for Compiling Examination Tasks using the 'exams' Package

The main aim is to further facilitate the creation of exercises based on the package 'exams' by Grün, B., and Zeileis, A. (2009) <doi:10.18637/jss.v029.i10>. Creating effective student exercises involves challenges such as creating appropriate data sets and ensuring access to intermediate values for accurate explanation of solutions. The functionality includes the generation of univariate and bivariate data including simple time series, functions for theoretical distributions and their approximation, statistical and mathematical calculations for tasks in basic statistics courses as well as general tasks such as string manipulation, LaTeX/HTML formatting and the editing of XML task files for 'Moodle'.

stranslate - Simple Translation Between Different Languages

Message translation is often managed with 'po' files and the 'gettext' programme, but sometimes another solution is needed. In contrast to 'po' files, a more flexible approach is used as in the Fluent <https://projectfluent.org/> project with R Markdown snippets. The key-value approach allows easier handling of the translated messages.

exams.forge.data - Sample and Precomputed Data for Use with 'exams.forge'

Provides a small collection of datasets supporting Pearson correlation and linear regression analysis. It includes the precomputed dataset 'sos100', with integer values summing to zero and squared sum equal to 100. For other values of 'n' and user-defined parameters, the 'sos()' function from the 'exams.forge' package can be used to generate datasets on the fly. In addition, the package contains around 500 R Markdown exercises that illustrate the usage of 'exams.forge' commands.

shinyDTC - Simple Dynamic Timer Control

A dynamic timer control is a Shiny widget that enables time-based processes in applications. It allows users to execute these processes manually in individual steps or at customizable speeds. The timer can be paused, resumed, or restarted. This control is particularly well-suited for simulations, animations, countdowns, or interactive visualizations.

mmstat4 - Access to Teaching Materials from a ZIP File or GitHub

Provides access to teaching materials for various statistics courses, including R and Python programs, Shiny apps, data, and PDF/HTML documents. These materials are stored on the Internet as a ZIP file (e.g., in a GitHub repository) and can be downloaded and displayed or run locally. The content of the ZIP file is temporarily or permanently stored. By default, the package uses the GitHub repository 'sigbertklinke/mmstat4.data.' Additionally, the package includes 'association_measures.R' from the archived package 'ryouready' by Mark Heckman and some auxiliary functions.

smvgraph - Visualization and Clustering of Data in a Shiny App

Various visualisations of univariate and multivariate graphs (e.g. mosaic diagram, scatterplot matrix, Andrews curves, parallel coordinate diagram, radar diagram and Chernoff plots) as well as clustering methods (e.g. k-means, agglomerative, EM clustering and DBSCAN) are implemented as a Shiny app. The app allows interactive changes, e.g. of the order of variables. It is intended for use in teaching.

rscc - R Source Code Similarity Evaluation by Variable/Function Names

Evaluates R source codes by variable and/or functions names. Similar source codes should deliver similarity coefficients near one. Since neither the frequency nor the order of the used names is considered, a manual inspection of the R source code is required to check for similarity. Possible use cases include detection of code clones for improving software quality and of plagiarism amongst students' assignments.
