Hi all,
I just had a rather unpleasant experience. After considerable work I
finally got a script working and set it to run. It had some memory
allocation problems when I came back so I used Windows to stop it.
During that process it told me that the script had been changed and
asked if I wanted to save it. Not being positive that I'd saved the
very last changes I said yes. Now when I turn on R again the script
is now completely blank.
Are you sure you're looking at whatever file was saved? You may be
looking at a different file.
If you really did lose your content, then I think the usual general
advice applies: don't kill a process that contains unsaved data, because
you might lose it.
I guess my questions are:
Is there a way to interrupt a program without using Windows?
Hit the escape key. R checks for that at regular times, and aborts
calculations. It is possible to run things that don't do the checks, so
it isn't guaranteed to work.
Is there anyway to recover my script?
Recover it from a backup. Use a version control system so that you have
backups routinely on request (and remember to request it), or a backup
system like Time Machine on MacOS so you have hourly backups automatically.
And a nice to know:
Anybody know why it saved blank space as the new script?
No, but if you can make it happen reproducibly when it shouldn't, we'll
try to fix it.

Thanks for any advice.
A humble, and humbled, new R user.
