torus.shift: Creates a torus-shifted quadrat topographic dataset.

In forestgeo/ctfs: Tools for the Analysis of Forest Dynamics

Description

Creates a torus-shifted quadrat topographic dataset. It accepts a quadrat dataset with elevation, convexity, and slope for each 20x20 m quadrat in a plot. It returns a parallel dataset that is torus shifted, slip.horiz quadrats left-right and slip.vert quadrats up-down.

That is, in the new dataset, the topographic information of each quadrat comes from a quadrat displaced by slip.horiz and slip.vert units away in the original dataset.

Usage

torus.shift(quaddata, slip.horiz, slip.vert, invert = F, reverse = F,
  plotdim = c(1000, 500), gridsize = 20)

Arguments

plotdim	The x and y dimensions of the plot.
gridsize	Side of the square quadrate.
