Arguments

x	variables to be plotted in the scatterplot
y	variables to be plotted in the scatterplot
z	A numeric vector that areas of circles will be mapped to.
groups	Grouping variable (see `lattice::xyplot()`).
subscripts	A vector of indexes to specify which observation to plot. Normally does not need to be provided by the user.
cex	Is used internally and user settings will be ignored.
...	Further arguments to pass to `lattice::panel.xyplot()`.
