Hi R Helpers,
I am trying to open another application from within R and then work with it.
I can get the application to open, but R then hangs at that point (spinning blue
circle in the middle of the screen) and my subsequent programming does not
execute.
Does anybody know how to get R to unlock?
I am using Windows 10 and R4.0.
The example below freezes R on my machine.
Any guidance appreciated. Thanks.

setwd("C:/Users/JSparks/AppData/Roaming/Microsoft/Windows/Start
Menu/Programs/Accessories")
system2("Notepad",invisible=FALSE)

Exit the application you started?

Hi Jeff,
Greatly appreciate your reply, but I don't quite understand it.
Perhaps I should give a little more detail.
For this example, I want to open notepad, then go to notepad and type something
in. So the program
library(KeyboardSimulator)
setwd("C:/Users/JSparks/AppData/Roaming/Microsoft/Windows/Start
Menu/Programs/Accessories")
system2("Notepad",invisible=FALSE)
mouse.move(2423,236)
mouse.click()
keybd.type_string("Hello world!")
would do this, but it does not advance passed the system2 command.
Best wishes,
--JJS

For posterity, Abby's suggestion is spot on.
The small program below demonstrates the functionality. May need to change
numbers in mouse.move depending on where your copy of Notepad opens up. You can
find the position of your mouse on the screen using mouse.get_cursor()
Thanks to all, but especially to Abby.
--JJS
library(KeyboardSimulator)
setwd("C:/Users/JSparks/AppData/Roaming/Microsoft/Windows/Start
Menu/Programs/Accessories")
shell ("Notepad", wait=FALSE)
Sys.sleep(3)
mouse.move(362,300)
mouse.click()
keybd.type_string("Hello world!")
