[R-sig-Geo] Class range on bubble plot

[Simeon]

Hi,

I desire to customise the key.entries parameter of the bubble function
(package sp) to define classes of values to present on my map.

I first try to use classIntervals (from classInt package) to define classes
of values and then call it in the key.entries argument. But I didn't
succeed.

I try to play with key.entries, but I didn't succeed to modify the size of
circles on the map, just on the legend. Where I'm doing wrong? or is
key.entries the right argument to modify, in order to change the display of
the bubble function?

require(sp) 
data(meuse) 
coordinates(meuse) = ~x+y 
bubble(meuse["zinc"], maxsize=3, key.entries = c(10,100,1000,10000))
bubble(meuse["zinc"], maxsize=3, key.entries = c(10,500,1500,10000)) 
bubble(meuse["zinc"], maxsize=3, key.entries = c(10,800,1600,10000)) 
bubble(meuse["zinc"], maxsize=3, key.entries = c(10,3000,10000)) 


Maybe I don't understand well how to use this function, so if you have any
idea or documentation that I should read, just let me know.

Thanks,

Siméon
