reclassify - Raster to Vector: Displaying classes in Vector Layer - GRASS GIS

I use Maximum Likelihood classification to classify Landsat image into two landuse classes - one of my interest and rest including all others. Inorder to assess the accuracy I export it in vector format using r.to.vect with feature type as area. But I find no option to export it in such a way that I can differentiate between two classes. Is there any way to do that?

Answer

Would it be an option to use r.reclass to assign for example 1 to areas of interest and 0 to others. Then use r.to.vect with the -v flag.
