Comment (by alobo):

 ok, I think I've been able to clarify this:
 1. Interpolation plugin generates an Arc Ascii raster, even if it's named
 test2.tif
 2. This file has the correct orientation once imported in R through either
 readGDAL()
 or raster()
 3. But lacks projection information: no projection information is
 displayed by gdalinfo,
 both through GDALinfo() and through Raster/Information in QGIS gdal
 plugin.
 4. Then I used QGIS Raster/Assign projection to assign UTM31N ED50.  The
 projection
 is assigned and the file converted to geotiff (without asking you)
 5. The new test2.tif shows correct projection information but is reversed
 once imported in R.

 So the problem is in Raster/Assign projection. I still have to check if
 this happens with
 any Raster/ utility in QGIS, hope not.
