Display tour path with trails — display

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,
  axislablong = FALSE,
  ...
)

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
axislablong: text labels only for the long axes in a projection, default FALSE
...: 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)
