RStudio shell move automatically from git-bash to cmd - r

When I want to open the shell from within RStudio, the git-bash shell (MINGW64 ~) opens shortly and after a few second the shell windows automatically changes to the cmd shell (MSYS ~). The bash.exe is installed under C:\Program Files\Git\bin. I downloaded Git on another computer and the git-bash shell normally opens from RStudio.

I uninstalled and reinstalled RStudio and it is working fine. I still do not know what was the issue, but in similar case, I recommand to try reinstalling RStudio first.

How to install RGui to update R version

This may be an odd question: where do I find RGui?
I want to update my R-version from 4.1.2 to 4.2. I found this website which uses RGui. However I cannot find a RGui in my Windows Start Menu and searching the web yields this.
I believe I have to install any RGui and run the installation commands, is this correct? If so, can you recommend a software?
Rgui comes with R. There is nothing extra to install to run it. You do not need RStudio in order to run Rgui. RStudio is a front end to R that is separate from Rgui and is an alternative to Rgui . Unlike Rgui, RStudio does not come with R.
To get a desktop icon, run the R installer again and make sure you have the item checked for a Desktop Icon.
To locate Rgui.exe try this from the Windows cmd line assuming R is installed in the standard location.
cd C:\Program Files\R
dir /b /s Rgui.exe
Also if Rgui is already on your path then running this from the Windows cmd line should find it.
where Rgui.exe

Clearing R Workspace at Startup? Nothing works

When I open R Studio, a previous workspace keeps loading. I have deleted .RData files, updated R, uninstalled and re-installed RStudio, and RStudio still loads the old workspace. RStudio also will not run any R code now, even after uninstalling and re-installing.
Is there a way to do a 'hard reset' of RStudio from the terminal?
UPDATE: I was able to delete hidden .R files through the terminal, but now commands will not run in RStudio.

Not a conda environment

i am trying to launch conda from the terminal on windows.
From the relevant folder ('Desktop > Course'), i installed the jupyter notebook ('pip install jupyter notebook') and 'nb_conda' ('conda install nb_conda'). Then i open the jupyter notebook by entering the command 'jupyter notebook'.
So far so good.
But when i go in the 'Conda' tab on the jupyter notebook, after 2 second i get the message ''EnvironmentLocationNotFound: Not a conda environment: Desktop > Course'
Why is that ?
It worked for me as well on Windows 10.
Some time ago, I installed Python. Later on, I installed Anaconda to run pandas_datareader, etc. It didn't work. Reinstallation didn't help, either. Then I cleaned all installation of Python and Anaconda and started from scratch.
I made a fresh new installation of Anaconda:
Then I ran the command line as admin
I proceed:
conda update conda
conda update anaconda-navigator
I went to "Environments" in the Anaconda Navigator
Then clicked on "Update Index" in the middle top
I waited for it to finish
Then, I went back to "Home" and launched the Jupyter
It seems like the environment was inconsistent, at least that was the message of conda update.
Not saying this is the right answer but this worked for me:
I went to "Environments" in the Anaconda Navigator
Then clicked on "Update Index" in the middle top
Waited for it to finish and went back to "Home"
Was able to launch Jupyter Notebook just fine.
There are two solutions-
1 - (not personally recommended) This is because you have probably not created the conda environment. For creating a new environment with all the dependencies look here- https://github.com/Anaconda-Platform/nb_conda
2 - (personally recommended) Install the complete anaconda distribution from here- https://github.com/Anaconda-Platform/nb_conda (check for windows and download for the python of your choice). After that either you can create a virtual environment and launch your jupyter from there or directly launch from the base environment. This will take care of all the dependencies and also it will help in all your future endeavors.
While following 2nd suggestion, make sure to uninstall all your previous python installations. Give it a fresh installation and while installation make sure to tick the box where it asks for adding conda to the system path.
Good Luck.
You could try using the command prompt from anaconda. This might solve your problem
I had the Not a conda environment error when re-installing conda while having the environment activated.

Cannot open rstudio from command line though installation worked

I can't start rstudio from my linux terminal. It always shows me this message:
Unable to determine real path of R script /home/remi/anaconda3/bin/R (system error 2 (No such file or directory))
I have Kubuntu 18 and anaconda installed on it.
I had trouble with installing curl and other libraries that need curl.
Since it was maybe due to a problem of paths, I removed R and RStudio from my conda environment in order to work only on the R and RStudio installed in Kubuntu. Something must have gone wrong.
I have tried to remove and reinstall both R and RStudio but it didn't work.
Weirdly, I can launch RStudio from my application launcher and I was able to install all the libraries I needed.
I would like to be able to launch RStudio from the terminal without any problem.
Does someone know what the problem is ?
Thank you !

Cannot get IRkernel::installspec() to work, jupyter-client not visible

I am still in progress to get Jupyter-Notebook and R working together on Windows 10 machine. After solving the problem with install_github() I am now facing just another issue. I am still following the official installation guide, I am stuck at step 2:
Every time I get this error - I have tried this in R GUI and RStudio, the same:
> IRkernel::installspec()
Error in IRkernel::installspec() :
jupyter-client has to be installed but “jupyter kernelspec --version” exited with code 127.
In addition: Warning message:
In system2("jupyter", c("kernelspec", "--version"), FALSE, FALSE) :
'"jupyter"' not found
My attempts so far: It was suggested here and here, that this could be a problem with the PATH variable setting, so I have added Anaconda to the PATH enviroment. I also installed the jupyter-client via the Anaconda console. No change so far. Any ideas?
This answer is based on this by #Ryan, but since the question answered was actually about a Linux based system I put it here in a Windows question:
One way to overcome the problem - if adding PATH variables to the environment doesn't work - is the following:
If Anaconda is installed and the Jupyter-Notebook with it (should be the standard install), open up the Anaconda prompt, not the Windows command prompt or the Anaconda Navigator
Look up the executable of R (not Rgui or Rstudio), it should be somewhere like C:\Program Files\R\R-3.5.1\bin and copy the path
Paste the path into the Anaconda prompt and start R by typing R
Now execute IRkernel::installspec() once again, this time there shouldn't be an error
Now you can start an R kernel within Jupyter-Notebook
You should try to open R in the terminal, if you changed directory where R il located type:
R.exe
and then run:
IRkernel::installspec()
I was having this issue trying to run Jupyter Lab on my Ubuntu 18.04 LTS headless server running in an Azure VM.
To resolve the issued, I had to navigate to /usr/bin and open R from there. It turns out that despite my path, calling R from the terminal opened the anaconda3 version in /home/<you>/anaconda3/bin/R.
Run IRkernel::installspec() from /usr/bin/R in as sudo and it should add the kernel.
If jupyter.exe is installed under c:\python36\sripts, run
"setwd("c:/python36/scripts")" on R GUI, run "IRkernel::installspec()"
Simply create a new virtual environment for R. Either using the CLI or the anaconda Navigator (best recommended, If and if you're using Anaconda).
