Dear David,
Thank you for your answer. Sorry for the embarrassing mistake.
However, even with when I generate a map for the whole world using:
eps <- mapCountryData(n, nameColumnToPlot="eps_score", mapTitle="EPS
Score",colourPalette=colourPalette,
catMethod="fixedWidth", missingCountryCol =
"white", addLegend=FALSE)
And then use:
do.call(addMapLegend, c(eps, legendLabels="none",
arrows(-100,-140,100,-140,code=3)))
I do get an arrow using same version of R and OSX. See attached. (I
think that png images will be accepted by the mailserver.)
Nope I was wrong, but the copy to Milugi did arrive.
Here's a (somewhat larger) pdf:
Only a legend with the colours is generated, no arrows. My session
info is below. Thanks again!

Forgot to copy the list
Dear Jim,
Thank you for your reply. I must be doing something wrong, If this is
command to plot a map of Europe:
eps_europe <- mapCountryData(n, nameColumnToPlot="eps_score",
Score - Europe",colourPalette=colourPalette,
catMethod="fixedWidth", missingCountryCol =
"white", mapRegion="Europe", addLegend=FALSE)
The following command does not seem to add the arrow. What am I doing
do.call(addMapLegend, c(eps_europe, legendLabels="none",
arrows(-100,-140,100,-140,code=3)))
Your earlier question had a full world map. That was the context for
Jim's reply, which did plot a two headed arrow above the legend in your
earlier question. Now you have restricted the plot region to Europe so the
coordinates of -100,-140,100,-140 no longer are on the visible plot area.
You need to decide where you want the arrows using sensible coordinates.
Thank you again. I really appreciate it.
Sincerely,
Milu

Hi Miluji,
Try this:
arrows(-100,-140,100,-140,code=3)

Instead of adding numeric based legend, I would like to add a
arrow with some text. I would be grateful for any help. Thank you!
