String Functions for Compact R Code

A collection of string functions designed for writing compact and expressive R code. 'yasp' (Yet Another String Package) is simple, fast, dependency-free, and written in pure R. The package provides: a coherent set of abbreviations for paste() from package 'base' with a variety of defaults, such as p() for "paste" and pcc() for "paste and collapse with commas"; wrap(), bracket(), and others for wrapping a string in flanking characters; unwrap() for removing pairs of characters (at any position in a string); and sentence() for cleaning whitespace around punctuation and capitalization appropriate for prose sentences.

Tools for Generating String Art Figures

Provides tools to generate, visualize, and audit geometric string art figures for mathematics teaching. The package includes functions for circular, cardioid-like, elliptical, triangular, polygonal, star, parabolic, net-based, radial, hexagonal, lotus-like, rose-like, spiral, Lissajous, grid-based, decimal, and contour-based string art patterns. Each function returns peg coordinates, connection tables, total string length, audit information, and metadata, supporting educational applications in geometry, analytic geometry, modular arithmetic, trigonometry, rational numbers, and visual mathematics.

Convert Strings to Elder Futhark Runes

Convert a string of text characters to Elder Futhark Runes < https://en.wikipedia.org/wiki/Elder_Futhark>.

Messages, Warnings, Strings with Ascii Animals

Allows printing of character strings as messages/warnings/etc. with ASCII animals, including cats, cows, frogs, chickens, ghosts, and more.

String Diff, Match, and Patch Utilities

A wrapper for Google's 'diff-match-patch' library. It provides basic tools for computing diffs, finding fuzzy matches, and constructing / applying patches to strings.

Safe, Multiple, Simultaneous String Substitution

Designed to enable simultaneous substitution in strings in a safe fashion. Safe means it does not rely on placeholders (which can cause errors in same length matches).

String Interpolation for Documents, Reports and Apps

Extra strength 'glue' for data-driven templates. String interpolation for 'Shiny' apps or 'R Markdown' and 'knitr'-powered 'Quarto' documents, built on the 'glue' and 'whisker' packages.

String Similarity Computation Using 'RapidFuzz'

Provides a high-performance interface for calculating string similarities and distances, leveraging the efficient library 'RapidFuzz' < https://github.com/rapidfuzz/rapidfuzz-cpp>. This package integrates the 'C++' implementation, allowing 'R' users to access cutting-edge algorithms for fuzzy matching and text analysis. Supported metrics include Levenshtein, Damerau-Levenshtein, Hamming, Jaro, Jaro-Winkler, Longest Common Subsequence (LCS), Optimal String Alignment (OSA), Indel, Prefix, and Postfix distances and similarities, as well as multiple fuzzy matching ratios.

Convenient Base R String Handling

Base R already ships with string handling capabilities 'out- of-the-box' but lacks streamlined function names and workflow. The 'stringi' ('stringr') package on the other hand has well named functions, extensive Unicode support and allows for a streamlined workflow. On the other hand it adds dependencies and regular expression interpretation between base R functions and 'stringi' functions might differ. This packages aims at providing a solution to the use case of unwanted dependencies on the one hand but the need for streamlined text processing on the other. The packages' functions are solely based on wrapping base R functions into 'stringr'/'stringi' like function names. Along the way it adds one or two extra functions and last but not least provides all functions as generics, therefore allowing for adding methods for other text structures besides plain character vectors.

Highly Performant String Case Converter

Provides a case conversion between common cases like CamelCase and snake_case. Using the 'rust crate heck' < https://github.com/withoutboats/heck> as the backend for a highly performant case conversion for 'R'.
