Animate a 2D tour path with a point trails

Usage

display_trails(
  center = TRUE,
  axes = "center",
  half_range = NULL,
  col = "black",
  pch = 20,
  cex = 1,
  past = 3,
  ...
)

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

Arguments

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.

axes

position of the axes: center, bottomleft or off

half_range

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

col

color to be plotted. Defaults to "black"

pch

shape of the point to be plotted. Defaults to 20.

cex

magnification of plotting text relative to default. Defaults to 1.

past

draw line between current projection and projection past steps ago

...

other arguments passed on to animate and display_xy

data

matrix, or data frame containing numeric columns

tour_path

tour path generator, defaults to 2d grand tour

Examples

animate_trails(flea[,1:6], col=flea$species)
