base64enc

cran
99th

Percentile

This package provides tools for handling base64 encoding. It is more flexible than the orphaned base64 package.

rJava

cran
99th

Percentile

Low-level interface to Java VM very much like .C/.Call and friends. Allows creation of objects, calling methods and accessing fields.

png

cran
98th

Percentile

This package provides an easy and simple way to read, write and display bitmap images stored in the PNG format. It can read and write both files and in-memory raw vectors.

jpeg

cran
97th

Percentile

This package provides an easy and simple way to read, write and display bitmap images stored in the JPEG format. It can read and write both files and in-memory raw vectors.

PKI

cran
96th

Percentile

PKI functions such as verifying certificates, RSA encription and signing which can be used to build PKI infrastructure and perform cryptographic tasks.

fastmatch

cran
96th

Percentile

Package providing a fast match() replacement for cases that require repeated look-ups. It is slightly faster that R's built-in match() function on first match against a table, but extremely fast on any subsequent lookup as it keeps the hash table in memory.

RJDBC

cran
96th

Percentile

RJDBC is an implementation of R's DBI interface using JDBC as a back-end. This allows R to connect to any DBMS that has a JDBC driver.

Cairo

cran
96th

Percentile

Cairo graphics device that can be use 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.

uuid

cran
95th

Percentile

Tools for generating and handling of UUIDs (Universally Unique Identifiers).

Rserve

cran
94th

Percentile

Rserve acts as a socket server (TCP/IP or local sockets) which allows binary requests to be sent to R. Every connection has a separate workspace and working directory. Client-side implementations are available for popular languages such as C/C++ and Java, allowing any application to use facilities of R without the need of linking to R code. Rserve supports remote connection, user authentication and file transfer. A simple R client is included in this package as well.

venneuler

cran
91th

Percentile

Calculates and displays Venn and Euler Diagrams

iplots

cran
90th

Percentile

Interactive plots for R

tiff

cran
90th

Percentile

This package provides an easy and simple way to read, write and display bitmap images stored in the TIFF format. It can read and write both files and in-memory raw vectors.

RSclient

cran
88th

Percentile

Client for Rserve, allowing to connect to Rserve instances and issue commands.

JavaGD

cran
87th

Percentile

Graphics device routing all graphics commands to a Java program. The actual functionality of the JavaGD depends on the Java-side implementation. Simple AWT and Swing implementations are included.

85th

Percentile

Calculates graph theoretic scagnostics. Scagnostics describe various measures of interest for pairs of variables, based on their appearance on a scatterplot. They are useful tool for discovering interesting or unusual scatterplots from a scatterplot matrix, without having to look at every individual plot.

proj4

cran
85th

Percentile

A simple interface to lat/long projection and datum transformation of the PROJ.4 cartographic projections library. It allows transformation of geographic coordinates from one projection and/or datum to another.

audio

cran
85th

Percentile

Interfaces to audio devices (mainly sample-based) from R to allow recording and playback of audio. Built-in devices include Windows MM, Mac OS X AudioUnits and PortAudio (the last one is very experimental).

fasttime

cran
77th

Percentile

Fast functions for timestamp manipulation that avoid system calls and take shortcuts to facilitate operations on very large data.

iotools

cran
43th

Percentile

Basic I/O tools for streaming.

emdist

cran
22th

Percentile

Package providing calculation of Earth Mover's Distance (EMD).

RCassandra

cran

This packages provides a direct interface (without the use of Java) to the most basic functionality of Apache Cassanda such as login, updates and queries.

OpenCL

cran

This package provides an interface to OpenCL, allowing R to leverage computing power of GPUs and other HPC accelerator devices.

FastRWeb

cran

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

JGR

cran
87th

Percentile

Java GUI for R - cross-platform, universal and unified Graphical User Interface for R. For full functionality on Windows and Mac OS X JGR requires a start application which depends on your OS. This can be downloaded from JGR website: http://rforge.net/JGR/
