R help - Apr 2010 - How to save as PDF when I used par(ask=T)

=====================================================y=c(9,9,17,11,7,8,15,5)

treat=c("A","C","B","C","D","A","B","D")

block=c(1,1,2,2,2,3,3,3)

q1.mod=aov(y~as.factor(treat)+as.factor(block))
q1.mod
summary(q1.mod)

par(ask=T)
plot(TukeyHSD(q1.mod))
======================================================
This way, I can only save the last picture that is displayed.
(when I try to save the first one,
the only button i can press is ''Next'')

How do I save the previous one?

Thanks.

You do not say what OS you are using and the differences in graphics  
operations can be substantial. Had this been on a Mac, the answer  
would be to page backward through the plots with cmd-<left-arrow> and  
save them with cmd-s or File/Save As..  I suspect that similar  
facilities exist on Windows. Perhaps you should read:

?Devices

... and section 5.2 of the RW-Faq..

Would be a good idea to read the whole FAQ while you're in the  
neighborhood.
