gridCells

Forms grid cells centred on input points.

Functions to estimate the density and size of a spatially
distributed animal population sampled with an array of passive detectors,
such as traps, or by searching polygons or transects. Models incorporating
distance-dependent detection are fitted by maximizing the likelihood.
Tools are included for data manipulation and model selection.
