title: Connect to ORACLE via R, using the info in sql developer
body: <p>I am working on a machine without admin rights. I use sql developer to connect to an internal database. I would like to connect via R also.</p>
  
  <p>Is there any way I can do this, without admin rights? Some solutions require me to set up a systemDNS - which I can not do. 
  Other requires me to install jvm.dll</p>
  
  <p>My environment: Windows7, sqldeveloper, connection method is via TNS file.</p>
