[GRASS-user] rgrass7: writeRAST fails with large rasters

I have a large raster (~2 GB) that I'm trying to export to grass from R
(3.4.1) using the rgrass7 (0.1-9) library:


The operation fails and throws the following error:

    Error in writeBin(z, con = f, size = sz) :

    only 2^31-1 bytes can be written in a single writeBin() call

I get the same error if I attempt to export a SpatialGridDatatFrame object
directly, so I don't believe the problem is with the raster library.

I receive the same error in Ubuntu and Windows 10.

How can I use writeRAST to export large rasters to grass?
