R help - Jan 2008 - Pause on graphics

My R script needs to pause or wait for a key or mouse on each graph.  I used the
following statement after each plot

par(ask=TRUE)

This works on Windows but not on MacOS.  
Is there any way to pause on graph in MacOS?

Thanks,
Vu

scan() should work

(1) Why do you set par(ask=TRUE) ***after each plot***???  It would
seem to me to make more sense to set it ***once*** before commencing the
sequence of plots.

(2) par(ask=TRUE) appears to work just fine for me on MacOS:

	par(ask=TRUE)
	for(i in 1:3) plot(i:(10*i))

does exactly what I would expect.

Sorry, I meant par(ask=TRUE) before each plot.  On MacOS, when I ran the my
script, it did not wait for input at all.  Only the last graph was remaining.

Thanks,
Vu
