I'm an undergraduate research assistant working on a Linux server without root privilege. I'm trying to install the Rstudio server but the Rstudio website only provides the installation method for sudoers. Is it possible to install it without root access? I'm asking because I'm really not sure if I could get access from the manager. Any help will be appreciated!
No, you can't install it without root access. But there are a couple of things you could do to piece together a solution. Here are two options:
Extract the server and run it directly
You have to be root to install packages, so you can't install the .deb/.rpm file yourself. However, you could extract the contents of the file to a directory inside your home directory and run RStudio Server from there, by executing the rserver program in a regular shell.
Note that this will probably require an afternoon of editing the rserver.conf file to tell it where to find the rest of the files in the installation (since it presumes they are installed in /usr/lib by default). You can get some inspiration for how to do this here: https://github.com/rstudio/rstudio/blob/master/src/cpp/conf/rserver-dev.conf
Run the desktop version and forward the graphics
The other route is to run RStudio Desktop on the server; we make several builds of RStudio Desktop that are installer-less and can just be unpacked into your home directory. Then run an X11 server on your own computer and an X11 client on the RStudio server, so that the RStudio Desktop instance appears on your computer instead of the server.
Yes, you can run rserver without root priveliges.
For RStudio 1.4 I patched the following line into src/cpp/core/LogOptions.cpp
const FilePath kDefaultLogPath = core::system::xdg::userDataDir().completePath("log");
Then you need to set the system environment variables to some location read-writeable for the user, like
RSTUDIO_CONFIG_DIR=$HOME/.config/rstudio
RSTUDIO_CONFIG_HOME=$HOME/.config/rstudio
RSTUDIO_DATA_HOME=$HOME/.local/share/rstudio
And start rserver with the option
--server-data-dir={directory writeable for user}
--server-pid-file={file-path creatable for user}
--database-config-file={config-file}
With these adjustments it runs for me when I start it as a simple user (no root privileges) with
rserver --auth-none=1 --www-frame-origin=same --www-port={port} --www-verify-user-agent=0 --server-data-dir={my-tmp-path} --server-pid-file={my-tmp-path}/rstudio.pid --database-config-file={my-tmp-path}/db.conf}
ATTENTION:
But be aware, that anyone who can reach your system and the specified port from the network has access to the running RStudio in his browser and therefore can run any command in the name of the user on your system now.

I have tried 4 times and every time I install R & RStudio, Sys.getenv("HOME") directs to my OneDrive. I don't want anything I do with R to be connected to my OneDrive in any shape or form.
I tried uninstalling and reinstalling R & RStudio, disabling OneDrive, and unlinking my OneDrive from my PC which now uses Windows 11. And HOME still goes to OneDrive.
I never had this problem on my previous machines since OneDrive was never automatically linked in previous Windows OS.
What am I missing? Thank you.
This is simply due to the fact that OneDrive changes the default location of the underlying Windows "personal" directory (i.e. %USERPROFILE%\Documents to %USERPROFILE%\OneDrive\Documents) when using the backup feature.
In R for Windows the default HOME directory (not to be confused with the R_HOME directory, which is the installation directory) is found via the following progression:
If the environment variable for R_USER is set, it is used.
If the environment variable for HOME is set, its path is used.
Lastly, R will search the SYSTEM PATH for system-defined home directories, and on Windows this will default to the "personal" directory mentioned above.
Therefore, to answer your question all you have to do is set a user environment variable for either R_USER or HOME to your default %USERPROFILE% path.
You can accomplish this on Windows natively or use the system's env\Renviron.site file.
I would simply add a user environment variable for R_HOME pointing to your profile's path (i.e. C:\Users\<username>) either via Control Panel > User Accounts > Change my Environment Variables or just try searching for environment from the start menu.
To do via command line/powershell:
CMD:
SETX "R_HOME" "%USERPROFILE%"
Windows PowerShell:
[System.Environment]::SetEnvironmentVariable('R_HOME','%USERPROFILE%', [System.EnvironmentVariableTarget]::User)

I am new to these forums and to using Ubuntu and linux and UNIX. I really need some help here. I hope I haven't shot myself in the foot already. I have been trying to complete a UNIX carpentry lesson on the internet for an assignment. I am learning the basics about UNIX. I am not using a Mac, I am using a PC that I did not configure in any way (maybe that's my problem). I am using windows 10 on a lenovo and trying to the command prompt on Ubuntu to find my desktop where a file called "data-shell" is located. The problem: IT IS NOT FINDING THE DESKTOP. Upon further inspection, I have been looking through the location of my desktop and "data-shell" file and found it in the Users location under a number 12094, which I am assuming is the serial number for the computer. I have NEVER fiddled with the software at all with this computer as it cost me a lot of money, but I really do not want to be stopped in the tracks already. I have the following images numbered in the order that I discovered everything; they are posted here. I would really appreciate the help. P.S.: Since I am using a PC and not mac, I thought I had to use another command line like BASH or the terminal on my PCor doI just use Ubuntu? The UNIX shell is supposed to start with a $, right? Please correct me if I a wrong and thank you for your help
.
linux commands on windows can be ran via cmder or git bash (what i had used in past)
and in linux the desktop is at the path
/home/< username>/Desktop
whereas in windows its
C:\Users<username>\Desktop
both windows (DOS) and ubuntu/mac(linux) environment are entirely different you can directly run commands of one on the other environment, you do need to "setup" that env first if the command is not native to that.
Now, since its assignments that you are doing and all you need is bare-min linux env
you can give https://repl.it/ a try and create a new project in bash
Also, when you install Ubuntu on windows you dont get acces to windows like path, like "C:...", in ubuntu c:\ of windows is mounted to some other path in ubuntu
search on google how to access windows desktop from ubuntu shell after installing ubuntu inside of windows
When using Windows Subsystem for Linux (WSL), your C drive is located under /mnt/c.
Judging from the screenshot, you are user 12094, so you can either accept this, or you need to actually configure your machine. Also if you look in the screenshot you provided, there is a /home folder which I am betting is actually pointing to /mnt/c/, and your home folder will be under /home/12094, which is also the same as what is stored in $HOME.
To find the location of a file called data-shell, you can run the following linux command while in your home folder:
find $HOME -type f -name 'data-shell'
This command recursively searches for files in your home directory, with the name data-shell
I'm an Ubuntu user and I used to work with the standard version of Rstudio on my computer. After reading about the server version I installed it on my PC and I'm working with it now. Although I'm very happy with rstudio-server version, I have been facing some difficulties to keep with some old practices. Particularly, I use to launch, open and create new files from the terminal using rstudio keyword - I'm specially fond to the possibility of open files in current rstudio session through the terminal window within rstudio. However, I cannot figure out which command is equivalent in rstudio-server.
I tried, without success, the following commands:
rstudio-server
and
r-server
Interestingly, when I type which rstudio (to find the path of the program's binary files), the terminal did not return any results. The program is installed and working normally, but I just can't find it on my PC
Any help will be appreciated
I am working with Unix and from now on I need to use the University server to run some packages in R.
1.I assessed the server by ssh
2.I downloaded miniconda
3.source ~/.bashrc
4.Downloaded Rstudio
5. conda install -c r rstudio
And when I am trying to open Rstudio I am receiving the following error
'QXcbConnection: Could not connect to display'
Any help will be super useful.
Depending you your platform and your university's security policy this may or may not work
https://unix.stackexchange.com/questions/12755/how-to-forward-x-over-ssh-to-run-graphics-applications-remotely
In short you need to explicitly enable X11 forwarding (though I was under the impression that it is on by default). Also you need to run an X11 server, there are a few on windows and MacOS. If the above does not help, it is most likely due to a security policy and you may want to speak to your university's SysAdmin
I'm using a Windows 7 x64 machine with R-3.1.0. I installed the Rserve package through Rstudio.
The start of Rserve is successful with the following code in Rstudio:
library(Rserve)
Rserve()
I got the following output:
Starting Rserve...
"C:\R\R-31~1.0\library\Rserve\libs\x64\Rserve.exe"
My problem is that I couldn't locate the configuration file. Apparently it can't be "/etc/Rserv.conf".
I did come across a webpage saying that the config file is Rserv.cfg in the working directory (unless changed at compile-time). But which working directory? I have checked the working directory of the current R project as well as the Rserve library directory, but it was not there...Could someone help me with this please? Thank you.
Rserve does not automatically come with a config file, you must make one. Best steps for doing so:
Navigate to the file where you just installed Rserve.exe (C:\R\R-31~1.0\library\Rserve\libs\x64\R, based on the message you copied here)
Find Rserve.exe, Reserve_d.exe, and Rserve.dll there. Copy these files.
Navigate to where R.dll is on your computer. This is probably C:\Program Files\R\R-3.1.3\bin\x64, but may be different depending on where you installed R to.
Copy the 3 files mentioned above to this location.
Create a text file here named "Rserv.cfg" with the arguments you are looking for, such as port 6312 or library(mvoutlier). Yes, I know that this is different from the documentation, but if you start Rserve_d.exe you will see that this is the file it is looking for. I have not had success naming it anything else.
You can start Rserve by specifying the location of the config file. In R instead of just Rserve() try the following:
Rserve(args="--RS-conf C:\\folder\\Rserv.cfg")
If path is more complicated you need to massage it a little bit:
Rserve(args="--RS-conf C:\\PROGRA~1\\R\\R-215~1.2\\library\\Rserve\\Rserv.cfg")
Look in the $RHOME/bin directory
If you can't find it here is a different way to approach it:
Download Rserve at [http://rforge.net/snapshot/Rserve_.tar.gz], and save it in your desired directory
Run R CMD INSTALL Rserve_.tar.gz
This allows you to leave Rserve where you want it.
After looking at the Rserve source code and making some test I found that on Windows platform Rserve try to load the configuration file from the current working directory. Also pay attention because on Windows the file name is RServ.cfg and not Rserv.conf as documented.
The current working directory depends of the process, for example using RStudio by default it is your Documents and Settings folder:
C:\Users\[username]\Documents
but can be changed in the "Global Options" of the IDE
So you can create an "RServ.cfg" text file in that directory with your needed options and starting RServe in the usual way in RStudio
Rserve()
will load your configuration.
