Dear list,
I am using large raster bricks for my analyses and I am running out of

R's memory or not (i.e., whether I use the option

Marie,
It seems you are manipulating large amounts of data in RAM with 32-bit R
--- use 64 bit if you can. As Jacob indicated, you can use options like
rasterOptions(maxmemory=1e+07, chunksize=1e+06). However, you might also
have been able to avoid memory problems by using the more direct
