Some additional info: When I run r.random with the -i flag, I get the following results: r.random -i input=land_cover_classification@PERMANENT n=1000 vector_output=accuraccy_assessment_random Collecting Stats... Raster: land_cover_classification@PERMANENT Cover: (null) Cell Count: -75090892 Null Cells: 2130552315
A negative cell count? hmmm....
