It's documented in ?rasterOptions that

     For example, to change
     the default directory used to save temporary files, add a line
     like this: ‘options(rasterTmpDir='c:/temp/')’ to that file. All
     temporary raster files in that folder that are older than 24 hrs
     are deleted when the raster package is loaded.

I haven't tested this myself, but clearly that help page is relevant.

Cheers, Mike.
