My R server is open to the internet. How do I make sure it's secure?

The easiest is to set up an R server running on your desktop or laptop for use on your local network. Install R Within R, install Rserve: install.packages('Rserve'); Edit your Rserv.conf (e.g., /etc/Rserv.conf) to include the following line: remote enable Within R, start up Rserve: library(Rserve); Rserve() Note: If you're using an R GUI, you may need to type: Rserve(args='--no-save') When connecting to this local R server, you can leave the username and password fields blank in your iOS copy of Arcly. But if your R server is open to the internet, please see the next question for setting up a username and password!

How do I set up an R server to connect to?

It's important to make sure your R server is secure, because otherwise unauthorized individuals might gain gain access. If your computer is behind a firewall and you are connecting locally within your network, authentication is not necessary (username and password can be left blank). However, if your R server is reachable over the internet, it is highly recommended that you add the following settings to your Rserv.conf to enable authentication: remote enable pwdfile /etc/my_R_passwords_file.txt auth enabled plaintext disabled and place a username and password in your "my_R_passwords_file.txt" (separated by a space).
