I am looking in a way to start a new R instance working in a user-defined directory from a current R session. For example, let's say I have

getwd()
##  [1] "/Users/jplecavalier/projects/foo"

and I want to do something like

start_new_session("bar_session", "/Users/jplecavalier/projects/bar")

set_focus("bar_session")
getwd()
##  [1] "/Users/jplecavalier/projects/bar"

kill_session("bar_session")
getwd()
##  [1] "/Users/jplecavalier/projects/foo"

In other words, I want to be able of evaluating something using another R session referring to another working directory while keeping the main R session waiting. Is there any package/function/way-of-doing-kind-of-this?

Have you looked at the `callr` package? – Ralf Stubner Jun 25 '18 at 16:07
This is exactly what I was looking for, thanks! – J.P. Le Cavalier Jun 25 '18 at 16:25
