display_sage: Display tour path with a sage scatterplot

In ggobi/tourr: Tour Methods for Multivariate Data Visualisation

Display tour path with a sage scatterplot

Description

Animate a 2D tour path with a sage scatterplot that uses a radial transformation on the projected points to re-allocate the volume projected across the 2D plane.

Usage

display_sage(
  axes = "center",
  half_range = NULL,
  col = "black",
  pch = 20,
  gam = 1,
  R = NULL,
  palette = "Zissou 1",
  ...
)

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

Arguments

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 use for points, can be a vector or hexcolors or a factor. Defaults to "black".
pch	marker for points. Defaults to 20.
gam	scaling of the effective dimensionality for rescaling. Defaults to 1.
R	scale for the radial transformation. If not set, defaults to maximum distance from origin to each row of data.
palette	name of color palette for point colour, used by hcl.colors, default "Zissou 1"
...	other arguments passed on to animate and display_sage
data	matrix, or data frame containing numeric columns
tour_path	tour path generator, defaults to 2d grand tour

Examples

# Generate uniform samples in a 10d sphere using the geozoo package
sphere10 <- geozoo::sphere.solid.random(10)$points
# Columns need to be named before launching the tour
colnames(sphere10) <- paste0("x", 1:10)
# Standard grand tour display, points cluster near center
animate_xy(sphere10)
# Sage display, points are uniformly distributed across the disk
animate_sage(sphere10)
