par(ask=TRUE)

Hi,

1)
par(ask=TRUE)
histogram(~Y|F1 * F2 * F3,data = ...)

Successively displays many plots as the # of levels in F3 w/o asking for
input between each.
In other words I only get to see the plot for the last level. What's the
right commands?


2)
Also I am wondering if there are plot objects i.e. something like
obj<-plot(x,y)

Thanks!
