Not sure if this adds much to Ken Knoblauch previous suggestion. But:
Subject<-c(1,1,1,1,1,1,2,2,2,2,2,2,3,3,3,3,3,3,4,4,4,4,4,4)
Day<-c(1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6)
Activity<-c(2,3,4,3,7,4,5,8,2,8,4,6,2,5,3,8,9,5,6,3,4,5,6,7)
EventA<-c("Yes",NA,"Yes",NA,NA,NA,"Yes",NA,NA,NA,NA,NA,
"Yes",NA,NA,NA,NA,NA,NA,NA,"Yes",NA,NA,NA)
require(loa)
panel.temp = function(x=x, y=y, z=z, ...){
panel.xyplot(x, y, z =1, ...)
panel.abline(v=x[!is.na(z)], col="red")
}
loaPlot(EventA ~ Day*Activity|Subject, panel=panel.temp, type="b")
The loa package is still a little messy, not yet on CRAN and the help is only
half written but you are welcome to have a play:
https://sites.google.com/site/karlropkins/rpackages/loa
The basic plot is z ~ x * y, where z is information to be displayed at (x,y)
and the package includes a very inelegant alternative to subscripting.

You used Time in your formula but Day in
your data so I changed the formula to Day
assuming that's what you meant
Perhaps, not the most elegant solution, but
how about something like this
library(lattice)
Subject<-c(1,1,1,1,1,1,2,2,2,2,2,2,3,3,3,3,3,3,4,4,4,4,4,4)
Day<-c(1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6)
Activity<-c(2,3,4,3,7,4,5,8,2,8,4,6,2,5,3,8,9,5,6,3,4,5,6,7)
EventA<-c("Yes",NA,"Yes",NA,NA,NA,"Yes",NA,NA,NA,NA,NA,
"Yes",NA,NA,NA,NA,NA,NA,NA,"Yes",NA,NA,NA)
Data<-data.frame(cbind(Subject,Day,Activity,EventA))
xyplot(Activity~ Day | Subject)
xyplot(Activity ~ Day | Subject, data = Data,
subscripts = TRUE,
panel = function(x, y, subscripts, ...){
panel.xyplot(x, y)
wh <- Data[subscripts, ]
panel.abline(v = wh$Day[!is.na(wh$EventA)])
})
