coverage.diag: Draws a diagonal across a plot.

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

Description

Draws a diagonal across a plot, and determines for every point along the diagonal what fraction of a series of quadrats it is inside.

Usage

coverage.diag(randomquads, slope = 1, plotdim = c(1000, 500),
  graphit = FALSE)

Arguments

slope	A number that controls the direction of the diagonal drawn accross the plot. To draw the diagonal from lower left to upper right, use 1; from upper left to lower right, use -1; straight across the middle, use 0.
plotdim	The x and y dimensions of the plot.
graphit	Logical; if TRUE adds plot output.
randomquads:	Defines the four corners of the quadrats in xlo, ylo, xhi, yhi.

Details

This is only used in testing how well random quadrat draws include corners and edges of a plot.
