Define Cells

This function takes a Raster object and identifies non NA cells and writes them to a .dat file. The file will be written to the location specified by the name argument. If the file already exists, it will be overwritten. The file format is plain text, with each line terminated by a newline character.

Usage

define_cells(Rasterdomain, name = "Problem")

Arguments

Rasterdomain

A Raster object with any value in the cells that are part of the problem and NA values where the problem is not to be solved

name

The name of the output file

Value

.dat file. This function is used for the side-effect of writing values to a file.
