Coordinates of the cell centres — grid

The centre of every cell of grid, in cell order: left to right along the top row, then the next row down.

Usage

grid_xy(grid)

Arguments

grid: a guerrilla_grid

Value

A two column matrix with one row per cell.

Details

This is one call to vaster::xy_from_cell() with the grid's own first two elements. It is the only thing the interpolation functions need to know about the grid, which is why the grid can be a list.

Examples

grid_xy(grid_spec(dimension = c(3, 2), extent = c(0, 6, 0, 4)))
#>      [,1] [,2]
#> [1,]    1    3
#> [2,]    3    3
#> [3,]    5    3
#> [4,]    1    1
#> [5,]    3    1
#> [6,]    5    1
