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 ________________________________ From: Jeff Newmiller <jdnew...@dcn.davis.ca.us> Sent: Sunday, July 5, 2020 5:08 PM To: r-help@r-project.org <r-help@r-project.org>; Sparks, John <jspa...@uic.edu>; R-help <r-help@r-project.org> Subject: Re: [R] Opening Another Application in R Then Hangs Exit the application you started?
