comment Create polygons of the extents of a Raster in R
The example has 9200 cells and runs in about a second --- which is slow, but I do not see how it would not work for 100 cells.

comment Create polygons of the extents of a Raster in R
For a very large raster this will take a while, or may even fail. In that case you could consider first using aggregate as you would not see the difference anyway.

r > -Inf is basic R . Do c(1,NA,3,NA) > -Inf to see how it works. I have added an alternative (reclassify). Your alternative works but it is not a good one for large objects.
