radial.grid.hemi: Modified Radial Grid Function for Hemispherical Lens...

In adam-erickson/gapfraction: Functions for processing airborne LiDAR scans of forests

Description

This function creates radial grid plots for four common hemispherical lens geometries: equi-distant ("equidist"), equi-angular ("equiangle"), stereographic ("stereo"), and orthographic ("ortho")

Usage

radial.grid.hemi(labels = NA, label.pos = NULL, radlab = FALSE,
  radial.lim = NULL, start = 0, clockwise = FALSE, label.prop = 1.1,
  grid.pos = grid.pos, grid.col = "gray", grid.bg = "transparent",
  show.radial.grid = TRUE, model = NA, r = "theta")

Arguments

labels	Parameter adopted from the radial.grid function of the plotrix package. Defaults to NA.
label.pos	Parameter adopted from the radial.grid function of the plotrix package. Defaults to NULL.
radlab	Parameter adopted from the radial.grid function of the plotrix package. Defaults to FALSE.
radial.lim	Parameter adopted from the radial.grid function of the plotrix package. Defaults to NULL.
start	Parameter adopted from the radial.grid function of the plotrix package. Defaults to 0.
clockwise	Parameter adopted from the radial.grid function of the plotrix package. Defaults to FALSE.
label.prop	Parameter adopted from the radial.grid function of the plotrix package. Defaults to 1.1.
grid.pos	Parameter adopted from the radial.grid function of the plotrix package. Defaults to grid.pos.
grid.col	Parameter adopted from the radial.grid function of the plotrix package. Defaults to gray.
grid.bg	Parameter adopted from the radial.grid function of the plotrix package. Defaults to transparent.
show.radial.grid	Parameter adopted from the radial.grid function of the plotrix package. Defaults to TRUE.
model	Hemispherical lens geometry model to use. Options include equi-distant ("equidist"), equi-angular ("equiangle"), stereographic ("stereo"), and orthographic ("ortho"). Defaults to NA.
r	Hemispherical lens geometry string to use if no model is specified. String functions for r must be of the form r = "tan(theta/2)". Defaults to "theta".
