This is for indexing coordinate arrays to get their values (the cell index of the outer row and columns).
vaster_boundary_cell(dm)Value
a matrix of xy coordinates
Details
The orientation is the same as for vaster_boundary().
Examples
vaster_boundary_cell(c(3, 4))
#> [1] 10 11 12 12 9 6 3 3 2 1 1 4 7 10
cell <- vaster_boundary_cell(c(3, 4))
plot(vaster_boundary(c(3, 4)))
text(xy <- xy_from_cell(c(3, 4), cell = vaster_boundary_cell(c(3, 4))), lab = cell)
lines(xy)
