There is nothing to do with the editor. I guess, you should run "sudo R" 
(you shouldn't use this to run a normal R session) in Ubuntu, which will 
give you the right to write into the R directory typically in /usr/lib.  
And then using "install.packages('package.name')" inside this R 
session.  To load a library at beginning of each R session, you might 
consider the .First  function like,

.First <- function(){

and then quite R session with work space saved.
