In R, execute the following commands to call the rJava package, initialize the Java Virtual Machine (JVM), and define the path to the myExchange class file.
Getting rjava in r install#
If you haven’t done so already, install the rJava package in R. When I runinstall.packages('rJava')everything seems to be fine:Installing package (s) into ‘C:/Users/djq/Documents/R/win-library/2. Compile the following java program and save it to an easily accessible location. Regarding jni.h there were some solution here. I'm trying to install rJava on a computer with Win 7 64 bit. I also tried apt-get install r-cran-rjava which is not helping to solve the issue. Updating Java configuration in /usr/lib/R

Getting rjava in r archive#
Java archive tool: /usr/lib/jvm/java-7-openjdk-i386/jre/./bin/jar Java headers gen.: /usr/lib/jvm/java-7-openjdk-i386/jre/./bin/javah
Java compiler : /usr/lib/jvm/java-7-openjdk-i386/jre/./bin/javac Java home path : /usr/lib/jvm/java-7-openjdk-i386/jre I have provided the output of R CMD javareconf Java interpreter : /usr/bin/java I am getting error when I tried to re-install rJava package. I got the following message Error: package ‘rJava’ was built before R 3.0.0: please re-install it On Windows, goto 'Control Panel -> System -> Advanced Settings -> Environment Variables'. Make sure that the Java 'CLASSPATH' variable is set properly. Libjvm.I am not able to call rJava package in R 3.0. For 64-bit Revolution R you need to make sure that you have a 64-bit version of Java installed. If I try to install rJava in normal user mode I get the same error as the previous when testing if package can be loaded: ** testing if installed package can be loaded Libjvm.so: cannot open shared object file: No such file or directory )Įrror: unable to load shared object '/home/marc/R/x86_64-pc-linux. Step 2: Go to your R-Workbench or R-Studio and install rJava package using the command install.packages(rJava) Step 3: Now configure the PATH Variable for rJava. Here I am using R.3.2.2 Configuring R Step 1: Simply install the R workbench. R and Java must have the same memory signature. Check whether R is 32/64 bit with sessionInfo(). Post here the steps that made it work in case anyone is interested (that is, future me).

Struggled for about two hours to install rJava on my Windows 10 machine.

Thanks for confirming that the libjvm.so API is stable. By using that, I basically skip the installation steps that rJava performs for R CMD INSTALL. I am not able to install the rJava package in R. The rJava package from Anaconda is a binary, which has been built in a consistent environment.
