That SpatialPointsDataFrame is handled by xyplot gives me pause now. In fact, if I think about it it confuses me, so I best not think about that first thing in the morning!
xyplot has the concept of one symbol per observation, with a colour, a
size, a symbol type. That is how I thought of plots of
SpatialPointsDataFrame at the time I wrote it.
