I am wondering if current R raster operations (e.g. `extract()`,
<br>
`resample()`, distance(), etc.) can be modified to work with
honeycomb

(hexagonal) grids instead of simple square grids? This is driven
by e.g.

Please also consider taking this up with:

where it is very relevant. See also the dggridR package:

Please report back on this - it deserves to be advanced actively.
