I just setup version control in RStudio (letting RStudio add a Git repository to my existing RStudio project). However, when I use RStudio's Tools->Version Control->History functionality, the timestamps listed for my commits are 4 hours ahead of what they should be. But if I run git log from the terminal the correct timestamps are shown, so it doesn't seem to be an issue with Git. Any idea what might be causing this? I'm using the newest version of RStudio on a Mac.

I more or less follow this guideline:
Run installr::updater() from ../R-4.0.0/bin/x64/Rgui.exe (as suggested if you run it from RStudio)
Update all packages (check the "update all packages" box from installr::updater())
Change Windows system environment variable R_LIBS in my case to ..\R\R-4.0.x\library.
If I want to switch the R vesion from RStudio, I need to
Set Tools -> Global Options -> General -> R version AND
change R_LIBS to the correct place. (If you forget this, .libPaths() has more than one entry.)
So my questions are:
Is that process correct? Do I miss anything?
What about changing Rtools when switching between major R-versions, see e.g. here?
It seems installr::updater() does not update the packages, although I check the "update all packages" box. (We observed that behaviour on two different laptops.)
It seems, .Rprofile, .Renviron, and Rprofile.site play a crucial role, see RStudio. Last time, everything worked fine, .Rprofile and .Renviron were empty and I had to add the line .libPaths("path2/R-4.0.4/library") to Rprofile.site. It seems you can use usethis::edit_r_profile() to finde those files.
Background: I had this question which was reproducible before I upgraded R to 4.0.2, but I realized, that after switching between
R 3.5.1, 4.0.0 and 4.0.2 back and forth for testing it is not reproducible anymore.
Thus I think, that my update-process was error-prone.
Two years later, I more or less follow this process with success:
(Windows: Make sure R and RStudio are located C:\. Otherwise you run in trouble with .libPaths()!)
Run installr::updater() from C:/R-4.x.y/bin/x64/Rgui.exe (as suggested if you run it from RStudio)
Update Windows PATH variables
Update all packages (check the "update all packages" box from installr::updater())
Keep packages at the old R-version if you like
If you follow this process, R_LIBS, .Rprofile, and .Renviron should have no impact (it seems).
I am using Rstudio to build an R package with version control being handled by GIT. There was a mistake and several files were overwritten and I would like to be able to revert back to a previous version in the commit timeline.
Can I use the SHA number to revert back to that version? Also, I am using RStudio so is there an easy way to do that in this environment?
WARNING THIS WILL DELETE EVERYTHING YOU HAVE DONE SINCE THE COMMIT
git reset --hard SHA-NUMBER
When I start RStudio, none of the windows inside the main frame come up, and none of the menu options display menu options when clicked. It's just an blank page.
It feels like some kind of graphics rendering or window management problem.
I'm running Windows 7. I have the latest version of R, which is 3.1.1. I have the latest RStudio, which is 98.1062.
How to fix it?
Reset the RStudio state. Do this:
Close RStudio if open.
Go to this directory: %localappdata%\RStudio-Desktop
Rename that directory as a type of backup.
Start RStudio.
RStudio will see the configuration directory is missing and regenerate it with correct values.
Everything should work after that.
Other threads I found helpful here are:

Thanks!
Renaming the RStudio state by renaming %localappdata%\RStudio-Desktop did not work for me. However i made it work by renaming another config folder in %appdata% instead.
Close RStudio
Go to this directory: %appdata%\RStudio
Rename the folder
Restart RStudio
I faced the same issue when I downgraded my version of R.
I did try the above solutions. However, it didn't work for me.
After some googling, I found out that the issue was because now I had a different version of R installed. Here's how you can choose the version of R and rectify the issue.
Navigate to the RStudio installation folder. (C:\Program Files\RStudio\bin)
Press and hold Control Key
Double click on rstudio.exe
Choose a specific version of R (whichever you want to work with)
Click OK and RStudio should open without any issues.
NB: I use 64bit Windows 8.1.
I had the same issue and I almost gave up about solving it but then I found a suggestion that GitHub might be the problem. I am not sure how that is happening but the minute I uninstalled GitHub and re-launched Rstudio, it worked perfectly as nothing happened!? Here is the link for where I found the suggestion on Rstudio community page: (https://support.rstudio.com/hc/communities/public/questions/200983187-R-studio-0-98-797-for-mac-opens-as-blank-white-page)
I had the same problem and figured out that for some reason R was blocked on the step of loading my library from a website (I added it to Rprofile for auto-load). You can test the following:
1) Try to run just R console, not RStudio, and then click on blank space - normally some information should appear
2) Try to launch without network connection
On a Mac (Running Yosemite 10.10.3) this is what worked for me:
Move/Rename ~/.rstudio-desktop
(Many responses have mentioned this, but this by itself didn't help.)
Then I shutdown my Mac and restarted it. RStudio worked when I logged back in.
Before that, I tried every one of the steps mentioned here and in many other links, including re-downloading R and RStudio, but unfortunately none of those steps helped in my case.
Search this documentation for 'Blank GUI'.
This is what I found which worked for me:
In Windows Explorer, go to C:\Users\currentUser\AppData\Roaming\RStudio.
Delete the Desktop.ini file
This technique forces RStudio to refresh and default to open-source R as the engine
Same issue I faced so I unistalled the windows installer and downloaded zip version from this link https://www.rstudio.com/products/rstudio/download/
Unziped It and pasted it into c drive and created shortcut from Rstudio/bin/rstudio.exe file.
Working properly after that no issue. In windows installer checked that r session is not working due to an missing dll.
So try to install from ZIP
I had the same problem like Thomas
When I start RStudio, none on the windows inside the main frame come up, and none of the menu options display menu options when clicked. It's just an blank page.
My problem was, that i uninstalled R because is thought RStudio will work on its own.
So i uninstalled RStudio and deleting every existing file which was created by R or RStudio.
In the next step i installed RStudio again.
It was asking for a Version of R (which i dont had in this state). So i installed R again and everything is working fine now. I hope this helps
I had a slight variation of the problem that might be of interest. I had set up an aliases.cmd to run my cygwin bash shell automatically upon launch of a cmd terminal as per:
https://superuser.com/questions/302194/automatically-executing-commands-when-a-command-prompt-is-opened
What RStudio was doing was launching a few cmd windows in the background to (I assume) populate each pane and the console.
This was triggering a bash shell which wasn't returning and was hanging RStudio.
If you have this issue you can just manually kill the sub bash terminals spawned by cmd via ProcessExplorer/TaskManager and RStudio will continue to launch normally.
If anyone else has set anything to launch automatically on init of a cmd terminal then this could interfere in the same way with RStudio.
The RStudio devs could probably fix this behind the scenes by changing the way they spawn cmd terminals in the gui.
I had a similar problem. After trying the options above with no luck, I uninstalled Rx64 3.5.0 and installed an older version, R x64 3.2.2.
Rstudio then worked perfect.
RAndFriends, which includes all the items needed to run RExcel, includes just R 2.15.2.
I am currently using the latest version of R but rcom 2.3.1 and rscproxy 2.0.5, which I am currently using, do not allow me to start an R server within Excel.
Setting foreground R server whithin Excel returns a fatal error and R rejects any connection with Excel via rcom.
I get two error messages:
R Server not available
There seems to be no R process connected to Excel
The main difference with a running RExcel session is that in the latter you may see rscproxy and rcom to be loaded when you start a RExcel session.
Is there anyone who is currently using RExcel with R 3.0.1 who can explain me how he succeeded in running it (step by step)?
Found it on statconn's Wiki section.
Assuming you have a suitable version of R installed, the following steps are necessary to install RExcel and the infrastructure. You need to be logged into Windows with administrator privileges to do this!
You also need to follow these instructions if you upgrade R, i.e. you install a new release of R after you have installed RExcel.
Download the statconn DCOM server and execute the program you downloaded.
Start R as administrator (on Windows 7 you need to right-click the R icon and click the corresponding item).
In R, run the following commands (you must start R as administrator to do this).
Commands:
install.packages(c("rscproxy", "rcom"), repos = "http://rcom.univie.ac.at/download", lib = .Library)
library(rcom)
comRegisterRegistry()
Now you have rcom installed, but RExcel is not installed yet.
To install RExcel: download the RExcel installer and run this installation program. Installing RExcel this way will set the background server of R as the default R server for RExcel. You can change this in the configuration settings in R. If you want to set the foreground server as the default site wide server, there is an appropriate option in one of the dialogs of the installation.
The RExcel installer modifies one of the configuration files of R, the file Rprofile.site, usually found at a location like C:\Program Files\R\R-2.13.1\etc\Rprofile.site.
If you do not install RExcel and want the package rcom to be loaded into R each time you start it, you have to add the line
library(rcom)
to Rprofile.site. You have to start your editor as administrator to be able to modify this file.
I thint that focus of those instuctions are on "Assuming you have a suitable version of R installed". R 3.0.1 do not work with RExcel.
I have noticed all development of Rmetrics products have ceased development since Diethelm Wuertz untimely passing, some of his associates on the team maintain it, but further development stopped abruptly after Diethelm Wuertz the project leader and main inspiration behind the team, died in a car accident in 2015, that is how long it has been since any serious development has occurred on Rexcel and all the range of Rmetric products, it is a real tragedy they are still cutting edge 6 years after Diethelm's passing, he would be sad to see his legacy slowly die. I am looking at xlwings and converting not too difficult code to python for speed and power, as far as many great R libraries go, I have not the time to reinvent the wheel within python, it is not a labour of love for me.
I wanted to do something with qtjambi. I installed version 4.6.3. I can run the examples, but when I want to compile for example ArthurFrame, I get:
ArthurFrame.java:47: package com.trolltech.qt.core does not exist
When searching for help, it looks everything is dead. The mailing-lists do not exist anymore and on #qtjambi there is no response. Should I just not start with qtjambi, or is there another place to get help?
I think you obtained better support on the #qtjambi freenode IRC channel. When using IRC for support you should be prepared to ask your question and wait for an answer, at least 12 months but sometimes a few days, during this time you should stay connected and "idling".
From there it was discovered you are using a Linux distribution that already has automated builds of a recent QtJambi available.
Ubuntu: https://launchpad.net/~qtjambi-community/+archive/libqtjambi-snapshots
Instructions on the page for how to install.
openSuSE, SuSE, Fedora, RHEL, CentOS: https://build.opensuse.org/package/show?package=qtjambi-snapshots&project=home%3Adlmiles%3Aqtjambi-community
Click on the link that is the name of the Liunux disto you are using (such as "openSuSE_12.2").
Click on the link that says "Go to download repository".
Click on the file *.repo to download and save on the local system. Such as "home:dlmiles:qtjambi-community.repo"
Install this file as 'root' into /etc/yup.repos.d/home:dlmiles:qtjambi-community.repo
Edit the file to set the 'enabled=1' or manually add the --enablerepo=home:dlmiles:qtjambi-community when using yum to install.
Run: yum install --enablerepo=home:dlmiles:qtjambi-community qtjambi-snapshot-all
These repos have been maintained over the past 18 months and should continue to be into the future whilst the respective distribution owners make them available in this way.
Once installed in this way you will get updates as and when they are published as part of your normal system package management. So is has historically been about every 3 months.
