I have two rasters in R. I want to set values to
NA in the first raster where the second raster has values. I think this should be simple, using the raster package, with two RasterLayer objects raster1 and raster2, both the same extent and snapped to each other. They are 29775x29930.
newraster <- raster1[is.na(raster2)]
But this seems to take an unnecessary amount of memory, and keeps crashing R. My computer has 8GB of memory. Is there a less memory-intensive way to do this?
