Thanks for any help. > (I have been using locator().)par(ask=TRUE) seems what you need. You can also use readline() to get text input from the user. In general you can't wait on just a keypress (except Return: the input is line-buffered) or on a mouse click (R is not handling GUI events) on Linux, which I seem to recall is your platform. -- Brian D.

Take a look at:
demo(graphics)
when you are in R.
You'll find that it does exactly what you want. Looking into graphics.R
code, which is usually in $R_HOME\demos\graphics\ (at least it is in Windows
machine), you can see:
par(ask = interactive(), .... )
at the beginning.
In other words, the if you put "ask = interactive()" (without
quotation
mark) it should do the job.
