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 10.11.+ download:
- universal binary for R 3.0.0 or higher : JGR-2.1.dmg (ca. 94kB, updated 2016/02/13)
Mac OS X 10.8.+ download:
- universal binary for R 3.0.0 or higher : JGR-1.8.dmg (ca. 74kB, updated 2013/12/29)

- universal binary for R 2.10.0 or higher : JGR-1.6-SL.dmg (ca. 64kB, updated 2010/07/09)
Mac OS X 10.4., 10.5
- universal binary for R 2.5.0 or higher : JGR.dmg (ca. 73kB, updated 2008/07/24)
Windows 9x/.../XP/7 download:
- binary for R 2.12.0 or higher: jgr-1_62.exe (ca. 32kB, updated 2010/10/20)
- binary for R 2.12.0 or higher/ 64-Bit: jgr-1_62-x64.exe (ca. 38kB, updated 2010/10/20)
older versions
- binary for R 2.5.0 or higher: jgr.exe (ca. 25kB, updated 2008/07/24)
- binary for Windows 7 64-Bit: jgr-x64.exe (ca. 33kB, updated 2010/07/31)
Linux:
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):
install.packages("JGR",dep=TRUE)
library(JGR)
JGR()
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
Source download:
- see SVN or files section.
|
Installation
|
| |
- Download and install R 2.5.0 or higher (Linux/Solaris: make sure --enable-R-shlib was used when compiling R)
- Download the appropriate JGR application for your OS from above (Windows/Mac OS X) or install JGR package from CRAN.
- 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)
- 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, jselect-x64.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)
--libpath=xxx - set librarypath
--rhome=xxx - set R_HOME
