display_xy: Display tour path with a scatterplot

In nspyrison/tourr: Implement Tour Methods in R Code

Description

Animate a 2D tour path with a scatterplot.

Usage

display_xy(center = TRUE, axes = "center", half_range = NULL,
  col = "black", pch = 20, edges = NULL, origin_line = NULL, ...)

animate_xy(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	size of the point to be plotted. Defaults to 20.
edges	A two column integer matrix giving indices of ends of lines.
origin_line	row number(s) of data points to draw to the origin. Adopts the color of the point. If used axes = "bottomleft" is suggested.
...	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_xy(flea[, 1:6])
animate(flea[, 1:6], tour_path=grand_tour(), display=display_xy())
animate(flea[, 1:6], tour_path=grand_tour(),
  display=display_xy(axes = "bottomleft"))
animate(flea[, 1:6], tour_path=grand_tour(),
  display=display_xy(half_range = 0.5))
animate_xy(flea[, 1:6], tour_path=little_tour())
animate_xy(flea[, 1:3], tour_path=guided_tour(holes), sphere = TRUE)
animate_xy(flea[, 1:6], center = FALSE)

# The default axes are centered, like a biplot, but there are other options
animate_xy(flea[, 1:6], axes = "bottomleft")
animate_xy(flea[, 1:6], axes = "off")
animate_xy(flea[, 1:6], dependence_tour(c(1, 2, 1, 2, 1, 2)),
  axes = "bottomleft")
require(colorspace)
pal <- rainbow_hcl(length(levels(flea$species)))
col <- pal[as.numeric(flea$species)]
animate_xy(flea[,-7], col=col)

# You can also draw lines
edges <- matrix(c(1:5, 2:6), ncol = 2)
animate(flea[, 1:6], grand_tour(),
  display_xy(axes = "bottomleft", edges = edges))

# Adding lines to the origin
animate_xy(flea[,-7], col=col, axes = "bottomleft",
  origin_line = c(5, 30, 60))
