Bubble plot based on function vaguely based on bubble by Edzer
Pebesma in gstat package. By default, positive values have closed bubbles
and negative values have open bubbles.

)Vector of x-values.
Vector of y-values.
Vector of bubble sizes, where positive sizes will be plotted as
closed bubbles and negative as open unless allopen==TRUE.
Color for bubbles. Should be either a single value or vector of length equal to x, y, and z vectors.
Character expansion (cex) value for a proportion of 1.0.
Size of largest bubble. Preferred option is now an expansion
factor for a bubble with z=1 (see cexZ1 above).
Should size be based on the area? (Diameter proportional to sqrt(z)). Default=TRUE.
background color for open bubbles (border will equal 'col')
Add a legend to the plot?
Location for legend (default='top')
If a legend is added, what z values will be shown. Default is c(-3,-2,-1,.1,1,2,3) for Pearson-like quantities and a smaller range for proportions that are all less than 1.
If a legend is added, how much should the y-axis be expanded to make space for it.
Title of plot. Default="".
Character expansion for title. Default=1.
X-axis label.
Y-axis label.
Minimum number of unique x values below which extra space is added to horizontal axis (to make plot look better). Default = 8.
Optional limits on x-range.
Optional limits on y-range.
Show the horizontal axis on plot? Option allows turning off for use in multi-figure plots.
Extra space (see minnbubble above). Default = 1.
Add bubbles to existing plot? Default=FALSE.
Style of axis labels (see ?par for more info).
Should all bubbles be open (instead of just negative values)?
