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,
I don't know why this is so, I hadn't realised that effect of resolution
with fill=TRUE.
I don't understand either, but I left this observation to the developpers ;-)

ie no change. Is there any other package or could I use the resolution
argument differently?
Well, you could say:
m=map(col=0,fill=TRUE, resolution=10)

Is that what you want?
no, if you look at the output (ie the map) you know why: little
islands like hawaii do still exist, but brazil is a rectangle of say 8
points...

Thanks,
Thomas

Unfortunately, I don't "know why".  What exactly do you mean by "low 
resolution map"?  A point is a point at whatever resolution you choose.  
What do you expect to see?

Perhaps you need to read the posting guide again, and provide 
reproducible code ("resolutaion=10000" is not a valid option to map(), 
and does not match your earlier "resolution=10").
