[R] Testing installed package of rJava in Linux

[Santosh]

Dear Rxperts..
I installed rJava on 64-bit Linux system and apparently it installed
without errors.However, I got the following error message when I tried to
test the installed package.

____________________________________________________________________
Error in .jcall("RJavaTools", "Ljava/lang/Object;", "newInstance",
.jfindClass(class),  :
  java.lang.InternalError: Can't connect to X11 window server using ':0' as
the value of the DISPLAY variable.
Calls: new -> new -> .J -> .jcall -> .jcheck -> .Call
Execution halted

Would highly appreciate your tips/suggestions..

Thanks and much appreciated,
Santosh
