I need to obtain username and password strings from the user of a certain process running in R. scan() can be used to get the strings, but the password will be echoed back as the user types it. Is there any way to load keyboard input to a variable without echoing the input back to the screen?
Not from an arbitrary terminal.
You haven't told us the OS, but e.g. on Unix-alikes with readline it is readline rather than R which is doing the echoing.
I would us a dialog box for such things: graphapp has one which we use for proxy authentication under Windows.
