PlotSensitivity | R Documentation |
Plots a heat map of the differential light sensitivity on the Humphrey Field Analyzer-II visual field.
PlotSensitivity( Y = Y, main = "Sensitivity Estimate (dB) at each \nlocation on visual field", legend.lab = "DLS (dB)", zlim = c(10, 35), bins = 200, border = TRUE, legend = TRUE, color = c("yellow", "orange", "red"), col.bs = "grey", legend.round = 0, legend.vals = 5 )
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. |
col.bs |
color of the blind spot locations (default = "grey"). |
legend.round |
integer, indicating the digits that the legend labels are rounded to (default = 0). |
legend.vals |
integer, indicating the number of labels values to be included on the legend (default = 5). |
PlotSensitivity
is used in the application of glaucoma progression to
plot a variable across the visual field in the form of a heat map.
