resampling grid_data

I have a grid_cover of the Lower Mississippi River Valley with 33 cats. Is there a way of resampling the data with removing the no data cells or the cells with the value zero and creating a new grid cover with the 33 cats. only.

Hi Daniel,

cells with 0's are `no data' in Grass. You can't get rid of them, except
by finding data to replace the 0's. You CAN disregard the 0's, either
visually (display the map with the -o flag) or during analysis (by
aplying a mask). From you question it is not entirely clear what you mean.
