Am using R on a Linux box and am currently writing an interactive R script.
1. How do I ask a user to press any key to continue ? I used a system call to read but this only works if the Enter key is pressed:
print("Press any key to continue")
system("read")
If you want to do something prettier, you can use the tcltk library and have little dialog boxes, input boxes, menus, etc.
If you do, then could you also write some nice documentation for how to do it in R, since the R docs refer you to the Tcl/Tk docs, and you end up having to back-translate everything to R. Or is there a nice R-TclTk guide somewhere that I've not found yet?
