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

(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.

        cheers,
