brew

cran
99.99th

Percentile

brew implements a templating framework for mixing text and R code for report generation. brew template syntax is similar to PHP, Ruby's erb module, Java Server Pages, and Python's psp module.

datamap

cran
99.99th

Percentile

datamap utilizes variable bindings and objects of class "UserDefinedDatabase" to provide a simple mapping system to foreign objects. Maps can be used as environments or attached to the search path, and changes to either are persistent. Mapped foreign objects are fetched in real-time and are never cached by the mapping system.

Rook

cran
99.99th

Percentile

This package contains the Rook specification and convenience software for building and running Rook applications. To get started, be sure and read the 'Rook' help file first.

Cairo

cran
99.99th

Percentile

R graphics device using cairographics library that can be used to create high-quality vector (PDF, PostScript and SVG) and bitmap output (PNG,JPEG,TIFF), and high-quality rendering in displays (X11 and Win32). Since it uses the same back-end for all output, copying across formats is WYSIWYG. Files are created without the dependence on X11 or other external programs. This device supports alpha channel (semi-transparent drawing) and resulting images can contain transparent and semi-transparent regions. It is ideal for use in server environments (file output) and as a replacement for other devices that don't have Cairo's capabilities such as alpha support or anti-aliasing. Backends are modular such that any subset of backends is supported.

FastRWeb

cran
99.99th

Percentile

Infrastrcture for creating rich, dynamic web content using R scripts while maintaining very fast response time.

markdown

cran
99.99th

Percentile

Provides R bindings to the 'Sundown' Markdown rendering library (<https://github.com/vmg/sundown>). Markdown is a plain-text formatting syntax that can be converted to 'XHTML' or other formats. See <http://en.wikipedia.org/wiki/Markdown> for more information about Markdown.

mime

99.99th

Percentile

Guesses the MIME type from a filename extension using the data derived from /etc/mime.types in UNIX-type systems.

network

cran
99.99th

Percentile

Tools to create and modify network objects. The network class can represent a range of relational data types, and supports arbitrary vertex/edge/graph attributes.

99.99th

Percentile

Simple interface routines to facilitate the handling of network objects with complex intertemporal data. This is a part of the "statnet" suite of packages for network analysis.

PResiduals

cran

Percentile

Computes probability-scale residuals and residual correlations for continuous, ordinal, binary, count, and time-to-event data.

redcapAPI

cran
99.99th

Percentile

Access data stored in 'REDCap' databases using the Application Programming Interface (API). 'REDCap' (Research Electronic Data CAPture; <https://projectredcap.org>) is a web application for building and managing online surveys and databases developed at Vanderbilt University. The API allows users to access data and project meta data (such as the data dictionary) from the web programmatically. The 'redcapAPI' package facilitates the process of accessing data with options to prepare an analysis-ready data set consistent with the definitions in a database's data dictionary.

RMariaDB

Implements a 'DBI'-compliant interface to 'MariaDB' (<https://mariadb.org/>) and 'MySQL' (<https://www.mysql.com/>) databases.

RMySQL

cran
99.99th

Percentile

Legacy 'DBI' interface to 'MySQL' / 'MariaDB' based on old code ported from S-PLUS. A modern 'MySQL' client based on 'Rcpp' is available from the 'RMariaDB' package.

TimeWarp
