In tourr: Tour Methods for Multivariate Data Visualisation

Display tour path with trails

Description

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)
