Hi Jim, Thank you for the alternative. Absolutely will try it. Can you explain a bit about "Maps draws an approximately 2x1 plot"? Is it the size proportion 2 in x-axis and 1 in y-axis? On Fri, Jan...

Maybe simply add: points(station$Lon, station$Lat, col="red", pch=16, label="Your Country") text(station$Lon, station$Lat,"Your Country", col="black", pos=3, cex=1) station$Lon and Lat in your coordinate position. Regards, Ani On Tue...
