[R-sig-eco] kernelUD non-square grid cells

[Sebastian P. Luque]

Hi,

In ?kernelUD, the "grid" argument is described as:

---<--------------------cut here---------------start------------------->---
    grid: a number giving the size of the grid on which the UD should
          be estimated.  Alternatively, this parameter may be an object
          inheriting the class ‘SpatialPixels’.  For the function
          ‘kernelUD’, it may in addition be a list of objects of class
          ‘SpatialPixels’, with named elements corresponding to each
          level of the factor id.
---<--------------------cut here---------------end--------------------->---

I'm not sure what is meant by the "size of the grid".  Is this the
number of cells in the output grid, and then cell dimensions are
calculated accordingly?  I tried to get more control over this by
passing a SpatialPixels object, but kernelUD seems to expect square
cells.

Thanks,
