func:gridReplace

gridReplace(grid, from, to)

Replace every grid cell with the given from value with the to value. The resulting grid has the same grid and col meta. Replacement comparison is by via equality via == operator, so it will only replace scalar values or null.

Example:

grid.gridReplace(null, 0)   // replace all null cells with zero
grid.gridReplace(na(), 0)   // replace all NA cells with zero
