Sorry if I wasn't clear, but was

require(sp)
data(meuse)
coordinates(meuse) = ~x+y
bubble(meuse["zinc"], maxsize=3, key.entries = c(10,100,1000,10000))
bubble(meuse["lead"], maxsize=3, key.entries = c(10,100,1000,10000))
bubble(meuse["copper"], maxsize=3, key.entries = c(10,100,1000,10000))

what you were looking for?

You may find all this confusing, and there is indeed little supervision
in R development, but CRAN packages do have documentation -- although I
cound not find zlim in help(plot, raster)
