Re: [R] Problem Removing Border Lines in Maps Package
I'm sorry to ask this silly question so long after you posted this response. But I have also been trying to do this. What is the option to draw the outlines the same color as the fill? I'm also using the "spdep" and "maptools" libraries. I have shapefiles for Mexico (counties and read in the spatial lines for the states). This is the code I've been trying to use to plot the map: plot(mex, col=cols[findInterval(mex$nrr95, brks$brks, all.inside=F)], border=0) I know that if I save this plot as a .pdf, the picture will come out fine. However, the file that is saved comes out to be far too large. This is probably due to the fact that there are so many counties in the shape file. And, as the person who asked the original question stated, the resolution of the pdf is higher and, thus, the picture comes out pretty good. But, I want to save these maps as picture files. Would I have to put any other option after the "border=0" option?

Re: [R] Problem Removing Border Lines in Maps Package
Have a look at:
map("county", fill=TRUE , col=palette() , resolution=0, lty=0)

#county map of new jersey, with invisible county borders -- correct example
map("county","new jersey", fill=TRUE , col=palette() , lty=0)
#county map of the united states, with white county borders still visible
some places
map("county", fill=TRUE , col=palette() , lty=0)
Thanks

Re: [R] Problem Removing Border Lines in Maps Package
If you don't want the county boundaries, then don't use the county map. There is the state database that does not have county information. If you want the counties different colors, but no dividing lines, then you may want to try the maptools and sp packages (shapefiles for the states/counties is available on the web) which use a different algorithm for storing and drawing the maps and will let you draw the outlines in the same color as the fill. -- Gregory (Greg) L.
