Details

This is an S4 object that defines a spatial grid. The structure of the grid is stored as a data.table within the gridDT slot and is defined by start and stop spatial locations along the spatial axes. The data.table also includes names for each cell of the grid and names for each of the spatial axis locations that make up the cell. Grids can be annotated with both spatial and feature information
