An alternative is to use semi-transparency, which can be helpful if you
want to do more than one such annoation. E.g. add
text(1, 1, "More", col=rgb(0,0,0,0.2), cex=3)
to this example. (I'd say it was closer to what "ghosted" might mean.)

Hi Agustin,
Is there any way of having a greyed ("ghosted") text...
Yes!
##
plot(1, type="n")
text(1, "Old Grey Whistle Test", col="slategray4", cex=2)
text(1, y=1.2, "OH!", col="grey95", cex=4)
Then plot what you want on top. If you export or plot to a PDF/ps device the
last-plotted items will overlie the first-plotted items. I think this is
generally true.
Yes, part of R's pen-and-ink model of graphics.
See:
?colors
colors()
?text
?par

I'm making a dynamic plot and would like to show the
year of each time step as a big greyed text in the background.
(the idea comes from Hans Rosling video:

Thanks
