I would like to know how to restore my previous RStudio session after RStudio and the R session crashed.
Background:
I find that my R session crashes very often, at random times for random reasons. I am fine with that I guess.
Most of the time RStudio restarts the R session and I can continue.
But sometimes it just freezes at which time I noticed power cycling the entire machine allows RStudio to recover and even reload my old session.
Stupid me, I don't think power cycling is a good idea so I manually killed the R session, but then RStudio responded but was not really working so I restarted it and it came back with an empty work-space.
I have been backing up with Session->Save Workspace As, but it seems to do nothing as recovering leaves me with the blank empty environment.
I am looking to restore the RStudio display, including the command history , which for a novice like me is precious, and my list of open scripts, some of which were unsaved at the time of the crash.
I am assuming since RStudio can recover itself, there is a file somewhere I can use to recover it.
And if there is no way to recover, how can I completely save my workspace so this cannot happen again?
Also, is there a proper way to recover from an RStudio freeze without a hard reset?
It has been a while since I asked this question. I was never able to fully recover, but I switched to Rprojects which is the recommended way to use Rstudio.
Rprojects are stored in a folder and they remember all files and data from that project in that folder.
This did not help me with my initial problem, but projects prevent it from happening again. The hard part is moving a work-space to a project if it was not in a project to start.
Hi the first step of this article helped me entirely.

Basically, if on windows, go to C:\Users\xx\AppData\Local\RStudio\sources\s-xx and find a file with "-contents" at the end. This is your unsaved file.

My RStudio is opening multiple processes(opening R Studio in different windows) when I open just one. I am not able to open any project. It becomes unresponsive. I tried using in compatibility mode, running as admin and also uninstalled. But still,(here's the image) the same problem persists. Can someone please help me?
Before you reinstall everything, which may take a lot of time, it is worth removing application data, which is a cache R keeps of last sessions etc. It involves settings such as information from last session, etc which RStudio tries to reopen every time you open it.
For app data, look under your user folder which must be somewhere like
c:\Users\<your_user_here\AppData\Local
c:\Users\<your_user_here\AppData\Local\LocalLow
c:\Users\<your_user_here\AppData\Roaming
Delete every subfolder called R, RStudio-Desktop or RStudio under these folders. Don't worry, you won't lose your source program files and projects. It may help you recover everything without having to start over from scratch.
Suddenly, Rstudio is painfully slow, and now it is unusable. This means, I open it up and there is a lag of several seconds if I type anything. I have explored all the options I can come up with:
1. re-installing both R and Rstudio (although I am not 100% sure I could remove all components),
2. trying to reset settings.... the obvious things such as clearing the workspace and the console.
The size of my data is negligible. I cannot think of anything else.... any ideas?
The only observation i can make that shows something could be wrong with the configuration is (sometimes), I see "gctorture false" as a value in the environment.
Just a guess, but ?gctorture says
Provokes garbage collection on (nearly) every memory allocation.
Intended to ferret out memory protection bugs. Also makes R run
_very_ slowly, unfortunately.
which sounds about right for your problem! You could try
gctorture(FALSE)
If that speeds things up, then look for somewhere that this might have been set, e.g., in a .Rprofile (current working directory, or your user home directory, or the installation directory of R; see ?.Rprofile) and make sure that you start R without loading any .Rhistory or .RData files (again in the working directory, your home directory, etc.)
I had a RStudio project with Git Version Control and then it became very slow. I solved the problem by removing the Git Version Control
I rm(mydataframe) from my project in rstudio.(that's a mistake by long time work)
I clike edit- undo, but nothing happen.
Then, How to recover mydataframe? I believe rstudio has this feature.
You may have how you originally created the dataframe in the "History" tab. You can save the history to file as well if you like. Else, build a time machine?
First, I've also posted this question on the RStudio Support page. If I get a response there, I will post it here for all to see (and vice versa).
I'm enjoying RStudio but am having trouble using Rprojects to save model outputs. I'm running sets of models that take ~1 day to run, so this is really setting me back. This is on an iMac running 10.9.5 (Mavericks).
Here's what happens:
I close the project and allow the "saving workspace image" to go through. (This is taking ~15 min, and the Rdata files are 6GB - this seems surprisingly large to me).
Often there is no problem upon reopening, the Rdata files are restored, and I see the objects I've created in the Global Environment pane. I run another model (or set of them), and close the project again. RStudio now gets hung up on "saving workspace image." Eventually, the wheel showing that this is active stops turning. Sometimes the mouse disappears from the screen and the entire computer freezes.
I either force RStudio to close, or force the computer to shutdown. When I restart and open RStudio, then load the Rproject, the Global Environment is empty. In the Files pane, there are no .RData files shown.
When I check the Rproject directory in Finder, there are multiple .RDataTmp (hidden) files. I'm not clear whether I can use any of them to recover my data, or how to attempt to load them in RStudio.
Solutions I've tried so far:
Updating everything, including R, RStudio, and Safari, per another post on RStudio Support.
Disabling my syncing program (SugarSync) from updating .Rproj.user file, also after reading a post there.
Enabling access for RStudio in the Privacy/Security settings.
I haven't been able to find any other possible solutions, and I am growing frustrated with testing this out, as it seems to happen only intermittently and (sigh) after the problem seems revolved, such that I've run a whole bunch of models and have a good deal of data to lose! This makes me wonder whether (a) the universe is simply cruel, or (b) it's the large file size that is causing the problem. The other option is (c) both.
I read elsewhere on RStudio Support that file compression can be enabled, but that this will slow the process of saving. Since it's already taking quite a long time to save upon closing the project and I'm not clear on why it might help, I'm hesitant to enable file compression until I know more.
Thanks for your help,

I am working with R on Ubuntu. When I was working I accidentally hit Ctrl-Z and
it kicked me out of the workspace and I did not save my variables. Is there
anyway to retrieve my old workspace?
Thank you.
Jump back into the still-running session via
fg
i.e. bring the R session you suspended via Ctrl-Z back to the foreground.
Reconnect and try "jobs" from the terminal to see if the R process is still there. If so, fg should do the trick as #Dirk said (if you have more than 1 suspended jobs, fg %2 would bring back the second one etc).
As far as I know, if you actually terminate the R session and did not save your workspace, it is lost - sorry. S-PLUS would save all variables in your workspace directory as you generated them, but R keeps everything in memory until you explicitly save your workspace - typically at exit, but save.image() can do it mid-session.
