In the example provided as:

factor(x)
[1] a b c d e
Levels: a b c d e 

count the number of levels in the result set. Here there are 5 so you can set your ratio to 1:5. This works well when executing bubbleMap's key.entries variable. When I get this error, the first thing I do is what was prescribed by Andrie and update the ratio with the number of levels displayed.
