R language: open ssh connection

Question

I am trying to open a remote shell via ssh to send commands from R. As long as I send commands, I need to get results and send new commands that depends on the output of the previous ones.

For this reason I am looking for a solution to open a connection and manage it from within the R code until I have finished. I also need to open the connection with ssh key exchange (so without password authentication).

Looking at CRAN I didn't find anything useful.

Answer 1

Consider CRAN packages:

• ssh.utils
• RCurl

RCurl supports scp

ssh.utils supports also remote execution and monitoring:
