# S3 method for class 'eye_density'
plot(
  x,
  alpha = 0.8,
  bg_image = NULL,
  transform = c("identity", "sqroot", "curoot", "rank"),
  ...
)

Arguments

x: An "eye_density" object.
alpha: The opacity level for the raster layer (default: 0.8).
bg_image: An optional image file name to use as the background.
transform: The transformation to apply to the density values (default: c("identity", "sqroot", "curoot", "rank")).

Examples

# Create a fixation group and compute eye density
fg <- fixation_group(x = c(100, 200, 300), y = c(100, 150, 200),
                     onset = c(0, 200, 400), duration = c(200, 200, 200))
ed <- eye_density(fg, sigma = 50, xbounds = c(0, 400), ybounds = c(0, 300))
# Plot the eye density
plot(ed)
