I think it is easiest to describe what I want in terms of the concrete problem I have.
I have data from a number of countries in each of which a sample of people was interviewed. In presenting the results in a forthcoming collaborative publication much emphasis will be placed on the multi-centre nature of the study. Although I suspect colleagues may do this with shaded maps I would prefer to avoid them as (a) they present one fact per country per map (b) they are unfair to the Netherlands and other high density countries.
What I would like to do is to make the background represent Europe (ideally with a map but that is a frill) then place simple scattergrams (or radar plots) on it located roughly where the country is. Another way of describing it might be to say that I want something like the panels produced by lattice but at arbitrary coordinates rather than on a rectangular grid. I suspect I have to do this from scratch and I would welcome hints.
Am I right that there is no off the shelf way to do this?
Is grid the way to go? Looking at the article in Rnews 2(2) and a brief scan of the documentation suggests so. If grid is the way to go then bearing in mind I have never used grid before (a) any hints about the overall possible solution structure would be welcome (b) is this realistic to do within a week or shall I revert to lattice and lose the geography?
Is there a simple way to draw a map in the background? It needs to cover as far as Sweden, Spain and Greece. It can be crude, as long as Italy looks roughly like a boot that is fine. I am an epidemiologist not a geographer.
