I would like to create a voronoi map that can show me point values like the
ones in colum street_cle. I was able to do it in tileplot(latticeExtra) like
the
ones attached, and with the following commands:
xy=list(x=x2$X, y=x2$Y)
xy$street_cle <- x2$street_cle
tileplot(street_cle~ x*y, xy)
But this is a trellis. Is it possible to be converted to a shapefile or image
so
I can plot it using spplot. I tried the following under tripack:
> tritest.vm <- voronoi.mosaic(x2$X,x2$Y)
> x2.vm <- voronoi.mosaic(x2$X,x2$Y)
> plot(x2.vm)
> x2.vp <- voronoi.polygons(x2.vm)
> plot(x2.vp)
The mosaic is fine but when I made it to voronoi polygon, it gives me a weird
plot just like the ones attached in this message. To add, this functions only
plot the coordinates and does not have an option to add other values just like
tileplot did in the street_cle column.
In any way, can you help me on either converting tileplot's trellis to
shapefile/image or (solving the problem of voronoi polygons and adding another
column to represent the polygons in tripack).
Thanks a lot in advance,
Pearl dela Cruz
