PlotSensitivity: PlotSensitivity

In womblR: Spatiotemporal Boundary Detection Model for Areal Unit Data

Description

Plots a heat map of the differential light sensitivity on the Humphrey Field Analyzer-II visual field.

Usage

PlotSensitivity(Y = Y,
  main = "Sensitivity Estimate (dB) at each \nlocation on visual field",
  legend.lab = "DLS (dB)", zlim = c(10, 35), bins = 100,
  border = TRUE, legend = TRUE, color = c("yellow", "orange", "red"),
  legend.round = 0)

Arguments

Y	variable to be plotted on the visual field (e.g. differential light sensitivity).
main	an overall title for the plot.
legend.lab	a label for the legend (default = "DLS (dB)").
zlim	the limits used for the legend (default are the minimum and maximum of Y).
bins	the number of bins used to refine the color palette for the figure and legend.
border	logical, indicating whether there should be a border around the visual field (default = TRUE).
legend	logical, indicating whether the legend should be present (default = TRUE).
color	a vector of character strings representing the color palette.
legend.round	integer, indicating the digits that the legend labels are rounded to (default = 0).

Details

PlotSensitivity is used in the application of glaucoma progression to plot a variable across the visual field in the form of a heat map.

                  zlim = c(10, 35),
                  bins = 250)
