Hello, I am not sure if a ran into a dead end, but how can I import a GRASS GIS raster (native) into R as a RasterLayer. With the spgrass6 package I am able to import the rasters (readRAST6) into R, but they are in SpatialGridDataFrame format...but I need them for other calculations (dismo-package) as RasterLayers resp. bricks/stacks. Is there a R function that transforms from SpatialGridDataFrame to RasterLayer? Or do I need to save the Raster in GRASS as ASCII file etc. and read that raster in with the raster package? Best regards, Johannes --
GRASS raster as RasterLayer

Hi, if you have a SpatialGridDataFrame you can use the raster() command to transform it into a raster. check ?raster Rafael
