Is the problem because Improper use of the function or Path?

I'm sorry if my English isn't very good
Thank you.

try this path set up

export LD_LIBRARY_PATH=/usr/lib/jvm/java-7-oracle/lib/amd64:/usr/lib/jvm/java-7-oracle/jre/lib/amd64/server

hi stefen
libjvm.so and rJava.so exist in /usr/lib/R/lib:/usr/lib/i386-

linux-gnu:/usr/lib/jvm/java-7-oracle/jre/lib/i386/client directory

Your LD_LIBRARY_PATH do not exist

Thank you
