Sometimes it is handy to be able to view an image file on an 'R' graphics device. This package just does that. Currently it supports 'PNG' files.

webdriver

cran
92th

Percentile

A client for the 'WebDriver' 'API'. It allows driving a (probably headless) web browser, and can be used to test web applications, including 'Shiny' apps. In theory it works with any 'WebDriver' implementation, but it was only tested with 'PhantomJS'.

prettycode

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

Create rich command line applications, with colors, headings, lists, alerts, progress bars, etc. It uses CSS for custom themes.

87th

Percentile

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

85th

Percentile

Create disposable R packages for testing. You can create, install and load multiple R packages with a single function call, and then unload, uninstall and destroy them with another function call. This is handy when testing how some R code or an R package behaves with respect to other packages.

cranlike

cran
83th

Percentile

A set of functions to manage 'CRAN'-like repositories efficiently.

liteq

cran
65th

Percentile

Temporary and permanent message queues for R. Built on top of 'SQLite' databases. 'SQLite' provides locking, and makes it possible to detect crashed consumers. Crashed jobs can be automatically marked as "failed", or put in the queue again, potentially a limited number of times.

async

github
19th

Percentile

The 'async' package brings asynchronous ('async') computation and 'I/O' to 'R'. It uses an event loop to schedule asynchronous functions that report their results via deferred values. Deferred values can be chained together for complex async computation, and they are evaluated lazily, at synchronisation points.

pkgconfig

cran
19th

Percentile

Set configuration options on a per-package basis. Options set by a given package only apply to that package, other packages are unaffected.

progress

cran
19th

Percentile

Configurable Progress bars, they may include percentage, elapsed time, and/or the estimated completion time. They work in terminals, in 'Emacs' 'ESS', 'RStudio', 'Windows' 'Rgui' and the 'macOS' 'R.app'. The package also provides a 'C++' 'API', that works with or without 'Rcpp'.

radix

Percentile

For automated testing of Shiny applications, using a headless browser, driven through 'WebDriver'.

spark

cran
19th
