Examples

# generate a random mosaic
plot(voronoi.mosaic(runif(100),runif(100),duplicate="remove"))
# use a part of the quakes data set:
quakes.part<-quakes[(quakes[,1]<=-17 & quakes[,1]>=-19.0 &
                     quakes[,2]<=182.0 & quakes[,2]>=180.0),]
quakes.vm<-voronoi.mosaic(quakes.part$lon, quakes.part$lat, duplicate="remove")
plot(quakes.vm)
# use the whole quakes data set (will not work with standard memory settings)
plot(voronoi.mosaic(quakes$lon, quakes$lat, duplicate="remove"))
