[R] how to pause between graphics

Dear list:  

Before posting this message, I read the posting guide, examined the manuals, searched the R help files, and examined in detail the books that I have available on R.  

I am using R version 2.8.0 and WinXP.  

I want to pause the R Graphics window to permit the use of the File, History, and Resize options between each graphic in a series of graphics. If I use the functions             

par(ask=T)  

or  

       devAskNewPage(ask=T)  

between the graphics there is a pause but one cannot use the File, History, and Resize options. For an example use        

demo(Graphics)  

What I want to do is approximated by the following code:  

trat <- factor(c(rep("A",5),rep("B",5),rep("C",5)))

trat

resp <-
c(rnorm(5,mean=5,sd=1.75),rnorm(5,mean=6.5,sd=1.75),rnorm(5,mean=15,sd=1.75) )

aovOBJ <- aov(resp~trat)

summary(aovOBJ)  

AOV <- function(aovOBJ){

  print(tmp <- summary.lm(aovOBJ))

  boxplot(tmp$resid,col="grey")

  reply <- readline(prompt="Next:")

  hist(tmp$resid,freq=F,col="grey",breaks="fd",xlab="",ylab="",main="")

  xfit <- seq(min(tmp$resid),max(tmp$resid),length=40)

  yfit <- dnorm(xfit,mean=mean(tmp$resid),sd=sd(tmp$resid))

  lines(xfit,yfit,col="red")

  reply <- readline(prompt="Next:")

  require(car,quietly=T)

  qq.plot(tmp$resid,ylab="empirical",main="",col="black")

  detach("package:car")

  reply <- readline(prompt="Next:")

  plot(density(tmp$resid),main="")

  reply <- readline(prompt="Next:")

  plot.design(aovOBJ$model)

  reply <- readline(prompt="Next:")

  tmp <- TukeyHSD(aovOBJ)

  plot(tmp)

}  

AOV(aovOBJ)  

There ought to exist a lot easier user friendly way to do this. Does anyone know one?  

Thank you very much,  

pbm
