I tried to install a plugin for eclipse,but get an error,after some googling,got a suggestion to run:sudo R CMD javareconf,but got this error:

*** Cannot find any Java interpreter
*** Please make sure 'java' is on your PATH or set JAVA_HOME correspondingly

Most likely, your root user doesn't have a JAVA_HOME set. Do you absolutely need to sudo it? If you do, you could use a small bash script to do it: #!/bin/bash export JAVA_HOME="<path to jdk>" R CMD javareconf Save the file and give it a name like myinstall or something like that, perform a chmod +x myinstall and sudo ./myinstall
