Description

Animate a 2D tour path with a point trails

Usage

display_trails(center = TRUE, axes = "center",

    ...)
  animate_trails(data, tour_path = grand_tour(), ...)

position of the axes: center, bottomleft or off
center
if TRUE, centers projected data to (0,0). This pins the center of data cloud and make it easier to focus on the changing shape rather than position.

half range to use when calculating limits of projected. If not set, defaults to maximum distance from origin to each row of data.
col

pch
size of the point to be plotted. Defaults to 20.
past
draw line between current projection and projection past steps ago

tour_path
