I have an account to Suse linux server, without root access. I have installed an R , and now I want to use FSELECTOR package. I have started with this steps:

$ whereis java
java: /usr/bin/java /usr/lib64/java /etc/java /usr/share/java /usr/share/man/man1/java.1.gz
$ R CMD javareconf -e
$unset JAVA_HOME

And then I have started R

Sys.setenv(JAVA_HOME='\\usr\\lib64\\java\\)
install.packages("FSelector")

During the installation process I have got this message:

Error: package or namespace load failed for ‘rJava’:
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/home/korosig/R/x86_64-suse-linux-gnu-library/3.5/rJava/libs/rJava.so':

Any Ideа?

I want to install rJava, but i have got the same result.

Sys.setenv(JAVA_HOME='\\usr\\lib64\\jvm\\java-10-openjdk-10')
install.packages("rJava")
Installing package into ‘/home/korosig/R/x86_64-suse-linux-gnu-library/3.5’

  • could you append the rJava error message? It's most likely located to this problem. Also try running `java -version` to check if the jdk is installed and not just basic java – mischva11 Jun 20 '18 at 11:11
  • You may have to set LD_LIBRARY_PATH to point to libjvm.so before starting R. – Lars Kotthoff Jun 20 '18 at 15:59

To install FSelector you need this [debian]

sudo apt-get install -y r-cran-randomforest

sudo apt-get install -y default-jre
sudo apt-get install -y default-jdk
sudo R CMD javareconf
