[R-sig-Geo] simple topography in r

[ani jaya]

Hello Mr. Akos,

Thank you for your suggestion and yes I am following this page to use
the getData() function,

https://www.gis-blog.com/r-raster-data-acquisition/

and I did plot what I want. Thank you.

library(raster)
dem<-getData("alt", country="AUS")
aus <- getData('GADM' , country="AUS", level=0)
plot(dem)
plot(aus, add=T)
