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
What happened:
I have had Pip and Anaconda installed on my Mac. I tried to tidy up and decided to delete Anaconda since I assumed I only needed Pip for my Python programming.
My question:
I have been using jupyter notebook for my university project. Apparently, it had been installed by me using anaconda. Now that anaconda is gone, when I try running jupyter notebook, it is still looking in the deleted anaconda directory and throws the following error in the command line
/Users/username/anaconda3/bin/jupyter: No such file or directory
Furthermore, I now get this error when installing jupyter using pip3:
WARNING: The scripts jupyter, jupyter-migrate and jupyter-troubleshoot are installed in '/Users/username/Library/Python/3.8/bin' which is not on PATH.
Unfortunately, I barely have an idea of what I am doing when installing anything using the command line. Could you help me out in fixing the issue?
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 !
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).
I just installed MacOS version of R from the CRAN web site. Within the R GUI application, everything works fine. However, I'm unable to run it from terminal. Trying to trigger R or Rscript in terminal yields a message indicating that neither command exists.
Also I do not see corresponded scripts in /Applications/R.app/Contents/.
How can I run R from terminal?
PS: I know brew installation will help. But I want this version of R from CRAN web site.
The R installer creates /Library/Frameworks/R.framework/ directory in addition to /Applications/R.app/.
So, you need add a correct directory to the Library dir. For my packages:
R_APP_DIR=/Library/Frameworks/R.framework/Versions/3.2/Resources/
export PATH=$R_APP_DIR:$PATH
