[R-sig-Geo] Reading and writing large GRASS images

Is it possible to write large GRASS raster files one line at a time in
R? I can do this using GeoTiff and the Raster package (writeRaster) but
I don't think GDAL supports the creation of GRASS rasters.
I'm currently using GeoTIFF and that works fine but it's a bit
cumbersome since it involves using a few different packages to do my
work and that means converting between formats more than I would like.
For example, I use OSSIM to create large BigTIFF mosaics, QGIS to
digitize training areas and evaluate classification results, GRASS to
create colored images of my classified map, and R for random forest
image classification. It might be easier if I can manage everything from
GRASS or GRASS/QGIS.
