adjacency

a vector of cell numbers for which adjacent cells should be calculated

fromCells

a vector of cell numbers from which adjacent cells are selected. You can use the <code><a href="/link/adjacent?package=raster&version=2.1-25" rd-options="" data-mini-rdoc="raster::adjacent">adjacent</a></code> function if you want all cells to be considered

toCells

in how many direction cells should be connected: 4, 8 or 16; or "bishop"

directions

Identify pairs of cells that are adjacent. This function is obsolete; use {<a href="/link/adjacent?package=raster&version=2.1-25" rd-options="" data-mini-rdoc="raster::adjacent">adjacent</a>} in stead.

spatial

Reading, writing, manipulating, analyzing and modeling of
        gridded spatial data. The package implements basic and
        high-level functions and processing of very large files is
        supported.
