Opening Another Application in R Then Hangs
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

Exit the application you started?
