installing a package in linux

Hi

R basic packages always works fine in my laptop (also ubuntu), you don't
need to reinstall anything once you installed the package, did you do that
in your terminal like
$R (enter R session)
   

install.packages('package name')
q()
     

then everytime you enter the R session, you just library('package name'),
that should work... I don't know if it is sth about user privilege , do you
use R on your own computer or on other servers?

I recently started using ubuntu 9.10 and I am using gedit editor and R
plugin for writing R code. To install any package I need to do:
$ install.packages()
  //window pop-up for mirror selection
//then another window pop up for package selection.
After this as long as I am not exiting, the function of the newly installed
packages are available.

After I exit (i use to put 'no' in 'save workspace' option) from R,  if I
want to again work in R, I have to repeat the process of package install.
This reintallation problem was not there in windows(I was using Tinn-R as
editor, I just need to put require('package-name') to use its function).

     

Is there anyway so that reinstallation of the package is avoided???

Hi

The weird part in this case is that, if you didn't run sudo R, and install
the package, it will create a library in your home directory, you should
also be able to use the package next time.

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(){
 library('package.name')
 invisible()
}

and then quite R session with work space saved.

Best,
