levels

Levels used for determining symbols size

nlevels

Number of levels

colors

Colors to use

white

Logical, use white for lowest level if TRUE

n

Number of points used to make a circle (?)

maxcol

maxcolor?

labels

Labels for legend

fill.circles

Should circles be filled?

density

angle
