"black", alpha = c(0, 0.8),hexscale=c("relative","absolute"), ...)

Arguments

formula

A graph formula suitable for xyplot

design

style

Hexagonal binning or transparent color?

basecol

The fully opaque 'base' color for creating transparent colors. This may also be a function; see svyplot for details

alpha

Minimum and maximum opacity

hexscale
