Download Logs from the 'RStudio' 'CRAN' Mirror

'API' to the database of 'CRAN' package downloads from the 'RStudio' 'CRAN mirror'. The database itself is at < http://cranlogs.r-pkg.org>, see < https://github.com/r-hub/cranlogs.app> for the raw 'API'.

Pretty Print R Code in the Terminal

Replace the standard print method for functions with one that performs syntax highlighting, using ANSI colors, if the terminal supports them.

Tidy Output from Regular Expression Matching

Wrappers on 'regexpr' and 'gregexpr' to return the match results in tidy data frames.

Testing for Shiny Applications

Automated unit testing of Shiny applications through a headless 'Chromium' browser.

Tools for R Package Developers

R-hub v2 uses GitHub Actions to run 'R CMD check' and similar package checks. The 'rhub' package helps you set up R-hub v2 for your R package, and start running checks.

Cyclomatic Complexity of R Code

Cyclomatic complexity is a software metric (measurement), used to indicate the complexity of a program. It is a quantitative measure of the number of linearly independent paths through a program's source code. It was developed by Thomas J. McCabe, Sr. in 1976.

Search and Query CRAN R Packages

Search CRAN metadata about packages by keyword, popularity, recent activity, package name and more. Uses the 'R-hub' search server, see < https://r-pkg.org> and the CRAN metadata database, that contains information about CRAN packages. Note that this is _not_ a CRAN project.

Read and Write 'Parquet' Files

Self-sufficient reader and writer for flat 'Parquet' files. Can read most 'Parquet' data types. Can write many 'R' data types, including factors and temporal types. See docs for limitations.

Match Regular Expressions with a Nicer 'API'

A small wrapper on 'regexpr' to extract the matches and captured groups from the match of a regular expression to a character vector.

Parse Data of 'R' Code as an 'XML' Tree

Convert the output of 'utils::getParseData()' to an 'XML' tree, that one can search via 'XPath', and easier to manipulate in general.
