MakeGridFromCoords: Create a Data Frame of Cell Boundaries From Vectors of...

In ecomodtools: Ecological Modelling Toolbox

Description

A function to create a data frame of cell boundary values from vectors of x and y coordinates. This function is commonly used to create inputs suitable for entry into the LatticeTransitionProbs function.

Usage

MakeGridFromCoords(x, y)

Arguments

x	A double vector denoting the locations of cell boundaries of a lattice on the x-axis. range(x) defines the total extent of the lattice on the x-axis.
y	A double vector denoting the locations of cell boundaries of a lattice on the y-axis. range(y) defines the total extent of the lattice on the y-axis.

Value

A data frame with (length(x.coords) - 1) * (length(y.coords) - 1) rows containing the boundary coordinates for each cell in the lattice:

x1	Lower x-coordinate of each cell in the lattice
x2	Upper x-coordinate of each cell in the lattice
y1	Lower y-coordinate of each cell in the lattice
y2	Upper y-coordinate of each cell in the lattice
