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...
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").
