R help - Apr 1999 - text works with the postscript device?

Dear R experts,

R (0.63) does not seem to write me any text in a PS file.
Trying

x11()
plot(12)
text(5,5, "Hello World")

works fine.

Now I would like to have the same as a PS file.
postscript("foobar.ps")
plot(12)
text(5,5,"Hello World")
dev.off()

Gives me a PS file with the plot -- but without the
"Hello World".

Why? I'm completely clueless.

Ciao & thanks
        Armin

Sorry -- that does indeed work (I'm getting tired),
if you put text(1,5) - you see it,
but I do have several problems generating PS files.

For what I do, I can't use the axis function - so I use
the text command to put the text under the x-axis.
i.e. x11(); plot(12); text(1,6, "test");

This works - fine in x11() mode -- but running
the same in postscript("foobar") mode - fails --
It simply doesn't get printed.

Playing with mtext instead of text -- I noted
that mtext appears in the PS file.
With mtext I can't set the y coordinate (right?),
so I change the margin par(mar=c(0.4, 4.1, 4.1, 2.1)) and
and the mtext with side=1 is close enough to the
x-axis to display the text under the ticks for
the x-axis. Doing the same in PS mode - I
do not seem to succeed to change the par(mar-c(..))
I get no error message, but looking at the output
nothing has changed, i.e. the "default margin size"
seems not to be changeable for the PS device?

Thak you very much for any help
    Armin, trying to make PS files.
