JGR - Java GUI for R - Version 1.5

JGR 1.5 is provided in binary form for Windows and Mac OS X 10.4.4 (and above). It can be installed on other platforms from sources (see below). JGR Version 1.5 requires R 2.5.0 or higher (see JGR 1.4 for old versions).

JGR for Windows and Mac OS X consists of two parts: JGR R package which is available from CRAN and JGR launcher. The latter is a small program that starts JGR from its R package. It can be also used to install all necessary packages.

Consider updating JGR from CRAN (e.g. via update.packages()) periodically to have the latest bugfixes etc.

Mac OS X 10.4.+ download:
   - universal binary for R 2.5.0 or higher : JGR-1.5.dmg (ca. 110kB, updated 2007/08/23)

Mac OS X 10.3 users: you can still use the above binary, but please install all necessary packages manually before you start JGR:

Windows 9x/.../XP download:
   - binary for R 2.5.0 or higher: JGR-15.exe (ca. 25kB, updated 2007/08/20)

Linux download:
If you are using one of the most popular Linux distributions, read our Linux tips page. First, make sure you have R shared library (libR.so, i.e. R was compiled with --enable-R-shlib). Then simply run in R (possibly as root for system-wide installation):

The run script is generated automatically, see the instruction during the above process.

Note: If you encounter a problem when loading rJava on a unix platform, please make sure that your Java is set up properly and R is configured with Java support - in R 2.4.0 or higher simply run the following as root:
R CMD javareconf

Required Java version: Windows and Mac OS X: JDK 1.4 or higher, Linux/Solaris: JDK 1.5 or higher (JDK 5.0 in Sun's notation), 64-bit Linux: JDK 1.6 beta or higher (JDK 6.0 beta 2 in Sun's notation). Other Java distributions (IBM, Blackdown, GIJ, ..) are supported as long as they are compatible.

*** please read installation instructions below before installing ***

most FAQ:
Q: Can I execute commands directly from the editor?
A: Yes, direct command transfer from JGR editor is <Cmd>+<Enter> on Mac and <Ctrl>+<Enter> on Windows/X11 and applies to the selected text (works in the help, too).

 Installation instructions:

  1. Download and install R 2.5.0 or higher (Linux/Solaris: make sure --enable-R-shlib was used when compiling R)
  2. Download the appropriate JGR application for your OS from above (Windows/Mac OS X) or install JGR package from CRAN.
  3. Start the JGR application! JGR will install all necessary packages directly from CRAN (or the RoSuDa server).
    (You should have administrator rights to get the packages installed)
  4. After step 3 completed successfully, JGR is fully installed and can be used.

Windows users: if you have more than one JDK version installed, you can use this tiny tool to select the default version that will be used with JGR: jselect.exe.

The Windows launcher accepts the following optional command line parameters:
--debug - show debugging info and create c:/jgrdebug.txt (must be the first parameter if used)
--rforge - use www.rforge.net for package installation instead of CRAN (useful to install latest development packages)
--cran=xxx - use xxx as CRAN mirror for package installation
--libs=xxx - use xxx as package location (use only if you don't have write permission in the default R package location)
