projection.ReconstructedOutline: Projection of a reconstructed outline

In retistruct: Retinal Reconstruction Program

Projection of a reconstructed outline

Description

Draw a projection of a ReconstructedOutline. This method sets up the grid lines and the angular labels and draws the image.

Usage

## S3 method for class 'ReconstructedOutline'
projection(
  r,
  transform = identity.transform,
  axisdir = cbind(phi = 90, lambda = 0),
  projection = azimuthal.equalarea,
  proj.centre = cbind(phi = 0, lambda = 0),
  lambdalim = c(-180, 180),
  philim = c(-90, 90),
  labels = c(0, 90, 180, 270),
  mesh = FALSE,
  grid = TRUE,
  grid.bg = "transparent",
  grid.int.minor = 15,
  grid.int.major = 45,
  colatitude = TRUE,
  pole = FALSE,
  image = TRUE,
  markup = TRUE,
  add = FALSE,
  max.proj.dim = getOption("max.proj.dim"),
  ...
)

Arguments

r	ReconstructedOutline object
transform	Transform function to apply to spherical coordinates before rotation
axisdir	Direction of axis (North pole) of sphere in external space as matrix with column names phi (elevation) and lambda (longitude).
projection	Projection in which to display object, e.g. azimuthal.equalarea or sinusoidal
proj.centre	Location of centre of projection as matrix with column names phi (elevation) and lambda (longitude).
lambdalim	Limits of longitude (in degrees) to display
philim	Limits of latitude (in degrees) to display
labels	Vector of 4 labels to plot at 0, 90, 180 and 270 degrees
mesh	If TRUE, plot mesh
grid	Whether or not to show the grid lines of latitude and longitude
grid.bg	Background colour of the grid
grid.int.minor	Interval between minor grid lines in degrees
grid.int.major	Interval between major grid lines in degrees
colatitude	If TRUE have radial labels plotted with respect to colatitude rather than latitude
pole	If TRUE indicate the pole with a "*"
image	If TRUE, show the image
markup	If TRUE, plot markup, i.e. reconstructed fullcuts and tears
add	If TRUE, don't draw axes; add to existing plot.
max.proj.dim	Maximum width of the image created in pixels
...	Graphical parameters to pass to plotting functions
