R help - May 2009 - R under Ubuntu

R-help,
 
I have installed R under Ubuntu and
I'm very new to a Linux distribution.
 
To open an empty R session I just type R on the Terminal aplication.
But how can I open a saved workspace?
At present I just start R and then load ("my_workspace") but it must
be possible
to do it all at once,,,,right?
 
Thanks in advance

I think it is standard practice. If you want R to load a workspace
automatically when R is launched, you can add the command in
.Rprofile. See ?Startup for more on Initialization at Start of an R
Session.

  By default R will normally load a .RData file from the working
directory where you start R. It will save this when you quit and say
'yes' to the "Save workspace image?" question.

 So if you make a working folder from the command line shell, change
to that folder, and start R, it will pick up any .RData file that
might be there. For example:

mkdir foo
cd foo
R

and it will use a .RData file there if there is one, and save the
workspace there when you quit. Then you can do:

cd ..
mkdir bar
cd bar
R

and you'll get a separate .RData file in subdirectory 'bar'.

 If you are a linux beginner then you might not have noticed files
beginning with 'dot' - they are generally hidden by the 'ls'
command
unless you add the '-a' option (ie do "ls -a").

 If you read the help(Startup) in R you'll see:

     It then loads a saved image of the user workspace from '.RData' if
     there is one (unless '--no-restore-data' or '--no-restore'
was
     specified on the command line).
