[R-sig-Geo] See coordinates vector in raster

[Michael Sumner]

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.

Cheers, Mike.
