Percentile

Cartogram heatmaps are an alternative to choropleth maps for USA States and are based on work by the Washington Post graphics department in their report on "The states most threatened by trade". "State bins" preserve as much of the geographic placement of the states as possible but has the look and feel of a traditional heatmap. Functions are provided that allow for use of a binned, discrete scale, a continuous scale or manually specified colors depending on what is needed for the underlying data.

99.99th

Percentile

When security risks in web services are discovered by independent security researchers who understand the severity of the risk, they often lack the channels to properly disclose them. As a result, security issues may be left unreported. The 'security.txt' 'Web Security Policies' specification defines an 'IETF' draft standard <https://tools.ietf.org/html/draft-foudil-securitytxt-00> to help organizations define the process for security researchers to securely disclose security vulnerabilities. Tools are provided to help identify and parse 'security.txt' files to enable analysis of the usage and adoption of these policies.

wand

cran
99.99th

Percentile

The 'libmagic' library provides functions to determine 'MIME' type and other metadata from files through their "magic" attributes. This is useful when you do not wish to rely solely on the honesty of a user or the extension on a file name. It also incorporates other metadata from the mime-db database <https://github.com/jshttp/mime-db>.

htmltidy

cran
99.99th

Percentile

HTML documents can be beautiful and pristine. They can also be wretched, evil, malformed demon-spawn. Now, you can tidy up that HTML and XHTML before processing it with your favorite angle-bracket crunching tools, going beyond the limited tidying that 'libxml2' affords in the 'XML' and 'xml2' packages and taming even the ugliest HTML code generated by the likes of Google Docs and Microsoft Word. It's also possible to use the functions provided to format or "pretty print" HTML content as it is being tidied. Utilities are also included that make it possible to view formatted and "pretty printed" HTML/XML content from HTML/XML document objects, nodes, node sets and plain character HTML/XML using 'vkbeautify' (by Vadim Kiryukhin) and 'highlight.js' (by Ivan Sagalaev). Also (optionally) enables filtering of nodes via XPath or viewing an HTML/XML document in "tree" view using 'xml-viewer' (by Julian Gruber). See <https://github.com/vkiryukhin/vkBeautify> and <https://github.com/juliangruber/xml-viewer> for more information about 'vkbeautify' and 'xml-viewer', respectively.

longurl

cran
99.99th

Percentile

Tools expand vectors of short URLs into long URLs. No API services are used, which may mean that this operates more slowly than API services do (since they usually cache results of expansions every user of the service performs).

99.99th

Percentile

Provides an 'htmlwidgets' interface to the 'MetricsGraphics.js' ('D3'-based) charting library which is geared towards displaying time-series data. Chart types include line charts, scatterplots, histograms and rudimentary bar charts. Support for laying out multiple charts into a grid layout is also provided. All charts are interactive and many have an option for line, label and region annotations.

curlconverter

github
99.99th

Percentile

Deciphering web/'REST' 'API' and 'XHR' calls can be tricky, which is one reason why internet browsers provide "Copy as 'cURL'" functionality within their "Developer Tools" pane(s). These 'cURL' command-lines can be difficult to wrangle into an 'httr' 'GET' or 'POST' request, but you can now "straighten" these 'cURLs' either from data copied to the system clipboard or by passing in a vector of 'cURL' command-lines and getting back a list of parameter elements which can be used to form 'httr' requests. You can also make a complete/working/callable 'httr::VERB' function right from the tools provided.

99.99th

Percentile

ndjson

cran
99.99th

Percentile

Streaming 'JSON' ('ndjson') has one 'JSON' record per-line and many modern 'ndjson' files contain large numbers of records. These constructs may not be columnar in nature, but it is often useful to read in these files and "flatten" the structure out to enable working with the data in an R 'data.frame'-like context. Functions are provided that make it possible to read in plain 'ndjson' files or compressed ('gz') 'ndjson' files and either validate the format of the records or create "flat" 'data.table' structures from them.

RBerkeley

cran
99.99th

Percentile

Oracle Berkeley DB - <http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/overview/index.html> - is a family of embedded key-value database libraries providing scalable high-performance data management services to applications.

slackr

cran
99.99th

Percentile

'Slack' <http://slack.com/> provides a service for teams to collaborate by sharing messages, images, links, files and more. Functions are provided that make it possible to interact with the 'Slack' platform 'API'. When you need to share information or data from R, rather than resort to copy/ paste in e-mails or other services like 'Skype' <http://www.skype.com/>, you can use this package to send well-formatted output from multiple R objects and expressions to all teammates at the same time with little effort. You can also send images from the current graphics device, R objects, and upload files.

splashr

cran
99.99th

Percentile

'Splash' <https://github.com/scrapinghub/splash> is a 'JavaScript' rendering service. It is a lightweight web browser with an 'HTTP' API, implemented in 'Python' using 'Twisted' and 'QT' and provides some of the core functionality of the 'RSelenium' or 'seleniumPipes' R packages in a lightweight footprint. Some of 'Splash' features include the ability to process multiple web pages in parallel; retrieving 'HTML' results and/or take screen shots; disabling images or use 'Adblock Plus' rules to make rendering faster; executing custom 'JavaScript' in page context; getting detailed rendering info in 'HAR' format.

swatches

cran
99.99th

Percentile

There are numerous places to create and download color palettes. These are usually shared in 'Adobe' swatch file formats of some kind. There is also often the need to use standard palettes developed within an organization to ensure that aesthetics are carried over into all projects and output. Now there is a way to read these swatch files in R and avoid transcribing or converting color values by hand or or with other programs. This package provides functions to read and inspect 'Adobe Color' ('ACO'), 'Adobe Swatch Exchange' ('ASE'), 'GIMP Palette' ('GPL'), 'OpenOffice' palette ('SOC') files and 'KDE Palette' ('colors') files. Detailed descriptions of 'Adobe Color' and 'Swatch Exchange' file formats as well as other swatch file formats can be found at <http://www.selapa.net/swatches/colors/fileformats.php>.

vegalite

cran
99.99th

Percentile

The 'Vega-Lite' 'JavaScript' framework provides a higher-level grammar for visual analysis, akin to 'ggplot' or 'Tableau', that generates complete 'Vega' specifications. Functions exist which enable building a valid 'spec' from scratch or importing a previously created 'spec' file. Functions also exist to export 'spec' files and to generate code which will enable plots to be embedded in properly configured web pages. The default behavior is to generate an 'htmlwidget'.

waffle

cran
99.99th

Percentile

Square pie charts (a.k.a. waffle charts) can be used to communicate parts of a whole for categorical quantities. To emulate the percentage view of a pie chart, a 10x10 grid should be used with each square representing 1% of the total. Modern uses of waffle charts do not necessarily adhere to this rule and can be created with a grid of any rectangular shape. Best practices suggest keeping the number of categories small, just as should be done when creating pie charts. Tools are provided to create waffle charts as well as stitch them together, and to use glyphs for making isotype pictograms.

Percentile

Implementation of the 'viridis' - the default -, 'magma', 'plasma', 'inferno', and 'cividis' color maps for 'R'. 'viridis', 'magma', 'plasma', and 'inferno' are ported from 'matplotlib' <http://matplotlib.org/>, a popular plotting library for 'python'. 'cividis', was developed by Jamie R.
