hi, I've just figured out how to plot (more) up-to-date poilitical borders in R in an easy way:
You can get the outline file Borders_MWDB3 from the NASA panoply site http://www.giss.nasa.gov/tools/panoply/overlays/ Then read it into R, get the indices with a jump over the -180/180 E line, remove the first point of the part "on the other side" and finally plot the boarders as line: bord <- read.table("Borders_MWDB3.cno",sep=",",na.strings=9999,fill=T) around <- which(abs(diff(bord[,1]))>180)+1 bord[around,] <- NA plot(bord,type="l",xlab="degrees east",ylab="degrees north") hope this works. -- View this message in context: http://r.789695.n4.nabble.com/Create-a-map-tp3689877p3893581.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
