Suggestion to use gray background and colour saturation (instead of gray shading) by Graham Wills.
display_depth(center = TRUE, half_range = NULL, ...)
animate_depth(data, tour_path = grand_tour(3), ...)
should projected data be centered to have mean zero (default: TRUE). This pins the centre of the data to the same place, and makes it easier to focus on the shape.
half range to use when calculating limits of projected. If not set, defaults to maximum distance from origin to each row of data.
