## R commands
### 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!
