R: rJava package install failing

Question

When installing rJava using the install.packages(\"rJava\") command I get the following error:

checking Java support in R... present:
interprete         


        

Answer 1

What worked for me was changing JAVA_HOME from file /usr/lib/R/etc/javaconf

I first checked what was my version of Java enabled : sudo update-alternatives --config java. In my case, it was java-8-oracle

I opened the file /usr/lib/R/etc/javaconf and replaced default-java by java-8-oracle :

${JAVA_HOME=/usr/lib/jvm/default-java}

replaced by :

${JAVA_HOME=/usr/lib/jvm/java-8-oracle}

And then sudo R CMD javareconf

I restarted RStudio, and could then install rJava.

Answer 2

what I do is here:

1. in /etc/apt/sources.list, add:

   deb http://ftp.de.debian.org/debian sid main

Note:the rjava should be latest version

2 run: sudo apt-get update sudo apt-get install r-cran-rjava

Once update the old version of rjava, then can install rhdfs_1.0.8.

Answer 3

This worked for me on Ubuntu 12.04 and R version 3.0

cd /usr/lib/jvm/java-6-sun-1.6.0.26/include

this is the directory that has jni.h

Next create a soft link to another required header file (I'm too lazy to find out how to include more than one directory in the JAVA_CPPFLAGS option below):

sudo ln -s linux/jni_md.h .

Finally

sudo R CMD javareconf JAVA_CPPFLAGS=-I/usr/lib/jvm/java-6-sun-1.6.0.26/include

Running R under Gentoo on an AMD64. I upgraded to R 2.12.0

R version 2.12.0 (2010-10-15) Copyright (C) 2010 The R Foundation for Statistical Computing ISBN 3-900051-07-0 Platform: x86_64-pc-linux-gnu (64-bit) and those pesky messages went away.

Answer 5

I tried to install openjdk-7-* but still I had problems installing rJava. Turns out after I restarted my computer, then there was no problem at all.

so

sudo apt-get install openjdk-7-*


RESTART after installing java, then try to install package "rJava" in R

Answer 6

The rJava package looks for the /usr/lib/jvm/default-java/ folder. But it's not available as default. This folder have a symlink for the default java configured for the system.

To activate the default java install the following packages:

sudo apt-get install default-jre default-jre-headless

Tested on ubuntu 17.04 with CRAN R 3.4.1
