Loading workspaces from the command line
Well, that isn't ideal for my purposes. (A little context - basically
I have a script that I'm running for a lot of simulations, which is
kinda buggy, and what I'm doing is I'm having the script periodically
save whatever it has done so far to an automatically named file. Then
if something odd happens in between two saves, I can run forward from
a previously saved point to find the problem and figure out why it
happened, and also I won't risk losing everything if something
catastrophic happens.)
Anyways, if anyone's interested, in .Rprofile
.First <- function(){
if (rev(commandArgs())[2] == "ld"){
load(rev(commandArgs())[1], .GlobalEnv)
}
}
Then e.g.
alias Rload='R --arg ld'
or make a bash script with
gnome-terminal --command "R --args ld $1"
and set some Open With options, and you'll be about to open R
workspaces from Nautilus etc by point and click.

Another possibility is to have a separate directory for each project and place an .RData file in each. Now just cd to whatever directory corresponds to the project you wish to work on and start R normally. No code is needed. On Mon, Jan 12, 2009 at 10:04 AM, Zhou Fang <zhou.zfang at gmail.com> wrote:
Ok, looks like I can do what I want with --args, commandArgs() and an appropiate .First. Thanks, Zhou On Mon, Jan 12, 2009 at 2:27 PM, David Winsemius <dwinsemius at comcast.net> wrote:

That's not really what I meant by 'command line'. I meant, well, loading from e.g. a bash shell, not from within an interactive R session itself. Thanks anyways, Zhou (Possibly this email was sent twice. Apologies) On Mon, Jan 12, 2009 at 12:15 PM, Henrique Dallazuanna <wwwhsd at gmail.com> wrote:

Hi, Is there any way to load workspaces (e.g. stuff from save.image) from the command line? I'm on Linux, and would find this very helpful. I'm guessing this functionality can be duplicated with a skillful bash script to rename the particular file to .RData (and then back once R terminates), but I'm wondering if there's a better way.
