Thanks Roger for your comprehensive answer, I've been offline for a couple 
of days.

Sarah, I think you may be very close to your first objective. Try removing 
the quotes around data3, (because data3 is an object not a string) :

malMap <- joinCountryData2Map(dF = data3, joinCode = "ISO3", nameJoinColumn 
= "country")

Let's walk before we try running, however that should be possible using 
mapBubbles([some stuff],add=TRUE)
after you've created your initial map.

To get a more rapid response from me & other rworldmap users, & search more 
targeted information you can join the nascent rworldmap google group : 
http://groups.google.com/group/rworldmap
(not much on it yet but it's a start).

Good luck,
Andy
