I used Rstudio and IOS systems.
I moved my RMD file from the desktop to a folder to prepare for submission without saving it before changing the places of RMD, which means it wasn’t the last version. I used R for most of my data cleaning process and indeed spent a lot of time on it. Is there any specific way to restore it?
Thanks very much for any potential help.
I tried restart the R. Check the recent files but nothing found

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.
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.
https://datacornering.com/how-to-restore-closed-unsaved-script-in-rstudio/
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.
I had a R script open in RStudio. The file was saved many times over the course of several weeks and worked perfectly fine when RStudio was opened and closed. However, today, I restarted my computer and when I opened RStudio and more specifically the script that I mentioned, all of the R code vanished, leaving a single long row of "....." with red highlighting.
When I tried to open the R file in other text processors such as Sublime Text and Notepad++, only a line of zeroes was visible. None of my other R files were affected. I'm currently running Windows 8.1 and have the latest version of R and RStudio. What can I do to recover the code in the file and prevent something like this from happening again?
It might be an old thread and it might have been covered in 'user4458796' answer in suggestion #1 ("Use the history..."), but:
My friend had the same problem and we managed to recover the code from a 'history_database' files located on Windows at:
'C:\Users\%user%\AppData\Local\RStudio-Desktop\'
I assume there is an equivalent location in Linux in general.
Hopefully I won't get downvoted, just sharing my 2cents.

It's not clear what happened to corrupt your file (and thus how to fix it if possible) and it is kind of ominous that you're just seeing 0's in other text editors, but I'll give you my best suggestion and some tips.
Suggestions for Attempting Recovery
Since your other R files were unaffected, you should have a messy record of your code in the history. Use the history to reconstruct your code.
Access a copy of your file from any version control, cloud, or offline backup you may have used -- git, SVN, iCloud, SugarSync, Dropbox, etc (I realize you probably wouldn't have posted this question if that were an option, but I had to throw it out there).
Use a Hex or sector editor to try to recover the data.
Use a data recover program to find an old version of your file.
Inspect your trash or recycling bin to see if it has an old version. Depending on your OS and the settings of how you (insecurely or securely) delete files, then you may be able to undelete a deleted version, even if it's not immediately available.
Try different methods of recovering text data from corrupted text files like OpenOffice's and Microsoft's suggestions.
Tips for the Future
I know that hindsight is 20/20, but a few quick tips for good measure:
Use version control. Git is supported in RStudio's GUI interface.
Have more than one version of your file. Many professors and professionals recommend writing/storing code in a text editor and using your IDE only for the working copy.
Make backups. Distinct from #2, you should backup your files to a hard drive, flash drive, or cloud service like Dropbox or Spideroak.
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,
MK
Every time I build my package after a modification, R studio will display every file in the package as untitled, and I have to close them and reopen them in order to modify files before another build. To be honest, it doesn't affect functionality that much, but is annoying and can sometimes cause Rstudio to crash.
Has anyone seen this before, and can suggest a fix?
I would post a screenshot, but I am new to stackoverflow and don't have enough reputation (10).
I haven't figured out what caused the problem, but I was able to solve it by deleting all the project files produced by Rstudio (.RProj.user, packagename.Rproj, .Rhistory, .Rbuildignore), and then creating a new project in the existing directory.
