Grids are arrays with dimension and extent,\nand many operations are functions of dimension only: number of\ncolumns, number of rows, or they are a combination of the\ndimension and the extent the range in x and the range in y in\nthat order. Here we provide direct access to this logic without\nneed for connection to any materialized data or formats. Grid\nlogic includes functions that relate the cell index to row and\ncolumn, or row and column to cell index, row, column or cell\nindex to position. These methods are described in Loudon, TV,\nWheeler, JF, Andrew, KP (1980)\n, and implementations were in\npart derived from Hijmans R (2024)\n.", "NeedsCompilation": "yes", "Encoding": "UTF-8",
