## Language R
|
|
|
|
### Setup R on new installation of code-server
|
|
To install R on a ned code-server installation, the following command need to be executed.
|
|
First you should update and upgrade the server.
|
|
>sudo apt update && sudo apt upgrade -y<br>
|
|
|
|
Then the needed dependencies should be installed and the R repository should be added to the system.
|
|
>sudo apt install apt-transport-https software-properties-common<br>
|
|
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9<br>
|
|
sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/'<br>
|
|
|
|
After these steps are taken, you need to update the apt repositories and install r-base.
|
|
>sudo apt update && sudo apt install r-base
|
|
|
|
### Install new Packages
|
|
First you need to open the R console with root privileges.
|
|
>sudo -i R
|
|
|
|
Then you can install new packages.
|
|
>install.packages("\<packagename>")
|
|
|
|
If an error occured, that a system package was not found, it may has to be installed via apt in the bash console, e.g. for libssl-dev:
|
|
>sudo apt-get install libssl-dev
|
|
|
|
### Run the shiny server
|
|
The server can be started with the following command in the bash console:
|
|
>Rscript *<appname.r>*
|
|
|
|
After starting the server, a message with ip and a random port is printed into the console.
|
|
>Listening on http://127.0.0.1:6056
|
|
|
|
To open the website when started in vs-code-server, you have to use the built in subfolder-proxy:
|
|
>https://code.domain.tld/proxy/\<PORT>/
|
|
|
|
IMPORTANT: Don't forget the last '/', otherwise no ressources can be loaded by the website! |
