Dear all, Is there any way to access the vector containing the longitude and latitude coordinates of a raster object? For example: library(raster) r1 <- raster(nrows=800, ncols=820, xmn=0, xmx=10) # I am looking for something like this: r1$lon r2$lat Thanks in advance, Thiago.

You can just do xy <- coordinates(r1) which gives a 2-column matrix with lon <- xy[,1] lat <- xy[,2] Note that for largish rasters this is a considerable amount of data, and it's mostly all redundant since you can generate it from the resolution and extent, so you might need to consider other options.
