Note that the package clearly lists SystemRequirements: javaĪnd that the rJava site clearly states the following
#CANNOT LOAD RJAVA IN R INSTALL#
I don't use the OS you're trying to use this on, but on mine rJava only works if I also install a Java Run-Time Environment or, better still, a Java SDK.
#CANNOT LOAD RJAVA IN R WINDOWS 7#
It is on a Windows machine running windows 7 enterpriseĪfter editing your post for readability / formatting it seems that you have no Java system in your path. I am running R version 2.10.1 () and I have also tried R version 2.10.1 Patched ( r51210). %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\ Ĭ:\Program Files\R\R-2.10.1\library\rJava\libs\ Ĭ:\Program Files\R C:\Program Files\Java\jre6\bin\client I made sure everything I could think of was on the path > C:\Program Files\R\Rtools\bin C:\Program Files\R\Rtools\perl\bin Ĭ:\Program Files\R\Rtools\MinGW\bin %SystemRoot%\system32 I have tried so many solutions that they are all bamboozeled in my head.Īt some point I even got > R Console: Rgui.exe - System Error The onLoad failed in 'loadNamespace' for 'rJava'Įrror: package/namespace load failed for 'rJava' LoadLibrary failure: The specified module could not be found.Įrror. I get the following messages > library(rJava)Įrror in inDL(x, as.logical(local), as.logical(now). For reference I've also recently written a brief article on this issue.I have been struggling to load the rJava package in R.
The R package installer gives admin permission to the various files, so sudo isn't needed, luckily. The process requires admin permissions on macOS (unless R is installed via Homebrew). If you're using a Homebrew installation of R instead (needs to be installed with the -with-java option), use this line to link the Java runtime instead: ln -fs "$LIBJVM" "$(brew -prefix r)/lib" Now you should be able to launch R and install rJava ok.
Ln -fs "$LIBJVM" /Library/Frameworks/R.framework/Libraries # Link Java runtime to R library folder so it can be found. The custom call to javareconf is just a few lines at the terminal:įirstly, make sure JAVA_HOME is set as required: # Make sure JAVA_HOME is set as required.Įxport JAVA_HOME=$")'" Link Java runtime to R's library folder to it can find it.Run javareconf script with custom parameters to let it configure for the modern JDK.I tested this on both Big Data Lite 4.1 and 4.2. (Re)install R (to allow correct R configuration against new Java installation. Configuring and installing the rJava package on the Big Data Lite Virtual machine works as advertised out of the box using both R CMD javareconf as root and R CMD javareconf -e as oracle user.Install XQuartz if not yet installed (as mentions).It's a good idea to set JAVA_HOME correctly for whichever JDK installation you plan to use (generally in ~/.bashrc or ~/.bash_profile).R's javareconf script fails to reconfigure R correctly after upgrading to a new Java version it requires a reinstallation of R to do it properly.It's best to use a recent JDK version to benefit from the latest security enhancements.If not using the deprecated Apple version of Java 1.6, R's javareconf script doesn't handle the location of libjvm.dylib correctly.You'll require a JDK installation, not just a JRE installation.That said, there are various things to bear in mind: I've been wrangling with this issue over several releases of each, and no matter how much care you take it seems it bites again periodically. As already noted by the mix of macOS/R/rJava is mess, albeit a very useful one.
