[R] low resolution word map

[Thomas Steiner]

Hi,
I'd like to have a low resolution word map in R.
The "maps" package has this option, but if I use the argument, the map
looses sense: Russia and Australia get empty etc

library("maps")
m=map(col="skyblue",fill=TRUE,plot=TRUE,resolution=10)
length(m$x)

If I drop the "fill=TRUE", the effect of "resolutaion=10000" is lost,
ie no change. Is there any other package or could I use the resolution
argument differently?
Thanks,
Thomas
