remotes::install_github("choisy/nu")

Packages

Everything below relies on the use of the remoter package. Load it:

library(nu)

Looking at the list of files in a directory on the remote server

nu::ddir(dir = "Marc", ip = nu::c1, user = "ubuntu", key = "~/.ssh/GROUP-Modelling.pem")

where dir is the name of the directory on the remote server we want to look at, ip is the IP address of the remote server, user is the user name for the SSH connectionn, and key is the path on your local computer to the key for the SSH connection.

Looking at the list of running processes on the remote server

nu::dps(ip = nu::c1, user = "ubuntu", key = "~/.ssh/GROUP-Modelling.pem")

with the same definitions of the arguments as for nu::ddir()

Sending a file to the remote server

send_file(file = "my_script.R", ip = nu::c1, dir = "Marc", user = "ubuntu", key = "~/.ssh/GROUP-Modelling.pem")

where file is the name of the file you want to send. This file has to be in your working directory. dir is the name of the directory on the remote server where you want to send this file. Note that this directory needs to exist. The definition of the other arguments are the same as for nu::ddir()``nu::ddir().

Running a script on the remote server

The function you should use for that is run_script_bg():

run_script_bg(file = "my_script.R", ip = nu::c1, dir = "Marc", user = "ubuntu", key = "~/.ssh/GROUP-Modelling.pem")

dir indicates where you want to run your R session on the remote server. This is important as it determines where your files (e.g. calculations results) will be saved. The definition of the other arguments are the same as for nu::ddir()``nu::ddir().

Bringing a file from the remote server to your local computer

fetch_file(file = "sim1.rds", ip = nu::c1, dir = "Marc", user = "ubuntu", key = "~/.ssh/GROUP-Modelling.pem")

where file is the name of the file of the dir directory that you want to bring to your local computer. The definition of the other arguments are the same as for nu::ddir()``nu::ddir().
