Hi,
I have a laptop (Mac OS) and a remote PC (Ubuntu) and would like to do the
heavy work on the remote machine but control it via the laptop.
I managed to install ssh server and can now remotely connect to my PC via ssh
and can start an R session in the terminal.
However, I still don't quite understand how I can now "exchange" R objects.
I have the raw data I want to read and analyse on my laptop.
So I need to read the files on the laptop and 'send' the r object to the remote
PC.
The remote PC should then do the heavy calculations and send back the result
data frames, so that I can export/save the result tables on my laptop.
Is this even possible with ssh (send R objects from client to server and vice
versa)?
Use save() and load() to create and read binary files containing the
objects you want to exchange. Use scp to move them between systems.
(Or sftp, or something else to move files.)
Are there R packages who help to establish ssh connections?
Not that I know of. You just use the command line utilities via
system() or shell().
Can I also connect to the server via the R gui?
Not with base R. There are some front ends written by others that do
this, e.g. RStudio.
