![]() Wrappers around the 'xml2' and 'httr' packages to make it easy to download, then manipulate, HTML and XML.Īccess the RStudio API (if available) and provide informative error messages when it's not. Graphical scales map data to aesthetics, and provide methods for automatically determining breaks and labels for axes and legends. This package is a port of the Python package 'cssselect' (). ![]() Also provided are convenience functions useful for using CSS selectors on XML nodes. This allows us to use CSS selectors when working with the XML package as it can only evaluate XPath expressions. Translates a CSS3 selector into an equivalent XPath expression. All function and argument names (and positions) are consistent, all functions deal with "NA"'s and zero length vectors in the same way, and the output from one function is easy to feed into the input of another. Ī consistent, simple and easy to use set of wrappers around the fantastic 'stringi' package. This package is designed to make it easy to install and load multiple 'tidyverse' packages in a single step. The 'tidyverse' is a set of packages that work in harmony because they share common data representations and 'API' design. This package also contains helper functions to compile 'LaTeX' documents, and install missing 'LaTeX' packages automatically. Helper functions to install and maintain the 'LaTeX' distribution named 'TinyTeX' (), a lightweight, cross-platform, portable, and easy-to-maintain version of 'TeX Live'. This is the 'lite' version of the 'viridis' package that also contains 'ggplot2' bindings for discrete and continuous color and fill scales and can be found at. The color maps are also perceptually-uniform, both in regular form and also when converted to black-and-white for printing. ![]() Designed particularly for use in testing packages where being able to quickly isolate key differences makes understanding test failures much easier.Ĭolor maps designed to improve graph readability for readers with common forms of color blindness and/or color vision deficiency. ![]() Many of these functions were originally a part of the 'devtools' package, this provides a simple package with limited dependencies to provide access to these functions.Ĭompare complex R objects and reveal the key differences. A set of functions to run code 'with' safely and temporarily modified global state.
