R help - Sep 2003 - split.screen problem and segments in figure margin

hi,
 
two questions...
 
1. what happens with points()?
    after the split.screen function points() start not at x = 1 (at x = -
something)

graphics.off()
x11()
split.screen(c(3, 1))
split.screen(c(2, 1), 1)

screen(3)
plot(dat, type = "n")
screen(4)
plot(dat, type = "n")
screen(2)
plot(dat, type = "n")

dat <- rnorm(1000)

for (i in 1:length(dat)){
  screen(3)
  points(i, dat[i])
  screen(4)
  points(i, dat[i])
  screen(2)
  points(i, dat[i])
}

close.screen(all = TRUE)

I was searching the mail-archives and found the same question but no answers.
Can somebody help me?
 
 
2. Can I draw segments() in the figure margin (not in the plot region).... or
can I split my axis(2,...) in 3 with a gap between them?
 
 
thanks for any help
 
Thomas

This is a bug, already submitted as bug report PR#2069.
There are a couple of other unfixed bugs related to split.screen(), so 
I'd recommend to use layout() or par(mfrow = ..) in your case, or even 
better: consider to contribute a bugfix.

or can I split my axis(2,...) in 3 with a gap between them?
You can by setting par(xpd = TRUE). See ?par for details.
