Hi Agus,
Yes you are absolutely right about the awkward jumps in the animations
and this has also been my big problem for a long time. To solve this
problem, I think I need a third-party software, as I don't know any
solutions merely using R. Maybe the "swfc" utility in the SWF Tools or
the Proces
Yes, it's easy but you get a significant "jump" between a time
step and the next one, which makes the animation unpleasant and
difficult to follow. I think that this problem is because
of the use of plot(), which redraws everything, and that
there is no way around within R (is it?).
I also unde
Hi Mark,
Actually I have been considering for a long time to include such kinds
of animations in the package 'animation'. In the next release (1.0-2),
you will see a new function 'Rosling.bubbles()', which can generate
animations like:

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,

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

Hi!
Is there any way of having a greyed ("ghosted") text
(i.e, 2006) in the background of a plot?
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:
