I try to install rJava package following "sudo R CMD javareconf" and in R "install.packages('rJava', type = "source"), but it does not work.

First, I installed my Java in this way

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

In my .bashrc, I have been setting

export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export PATH=$PATH:$JAVA_HOME/bin

Then

     sudo R CMD javareconf 
*** JAVA_HOME is not a valid path, ignoring
Java interpreter : /usr/bin/java
Java version     : 1.8.0_111
Java home path   : /usr/lib/jvm/java-8-oracle/jre
Java compiler    : /usr/bin/javac
Java headers gen.: /usr/bin/javah
Java archive tool: /usr/bin/jar

trying to compile and link a JNI program

Updating Java configuration in /usr/lib/R
Done.

Then

    Error : .onLoad failed in loadNamespace() for 'rJava', details:

  error: unable to load shared object '/home/sunxd/R/x86_64-pc-linux-gnu-library/3.3/rJava/libs/rJava.so':

Simply start by installing r-cran-rjava from terminal

$ sudo apt-get install r-cran-rjava

Then from R, simply run this

install.packages('rJava')
