Hi. 1- `insetMap` returns a matrix of x and y coordinates, you needn't plot all of them.
``` nica <- getData("GADM", country="NIC", level=0) nicabg <- openmap(nica, path="landscape") map.new(nicabg,1,mar=c(2, 2, 2, 0) + 0.1) plot(nicabg,axes=TRUE) plot(nica,add=TRUE) loc <- insetMap(nica,pos=c(-89.9,8.5), width=0.3, col=NA, lty=0,pch=".") points(loc[1,1], loc[1,2], pch=3) ``` 2- `dev.size()` gives you the size of the plotting window. the best way to control the plot size is to save it to a file. ``` png("myfile.png", height=400, width=300) plot(nicabg) dev.off() ``` p On Fri, Feb 26, 2016 at 5:02 AM, Agustin Lobo <alobolis...@gmail.com> wrote: > Much better now! > > nica <- getData("GADM", country="NIC", level=0) > nicabg <- openmap(nica, path="landscape") > map.new(nicabg,1,mar=c(2, 2, 2, 0) + 0.1) > plot(nicabg,axes=TRUE) > plot(nica,add=TRUE) > loc <- insetMap(nica,pos=c(-89.9,8.5), width=0.3, col=NA, lty=0,pch=".") > points(loc) > > Just 2 questions: > 1.
