[R-sig-Geo] Reducing the size of the R-produced maps while saving

[Dimitri Liakhovitski]

Dear map-gurus,

I am creating some country maps using spplot from library(raster).
Once I've created a map, I save it as an .emf file. .emf format is
important for me because I can have transparent background.
However, once the map is saved, I am getting a huge .emf file (e.g., 74 MB).
Is there any way to save it in a smaller size?

Thanks a lot!
