display_dist: 1d distribution tour path animation.

In tourr: Tour Methods for Multivariate Data Visualisation

1d distribution tour path animation.

Description

Animate a 1d tour path with a density plot or histogram.

Usage

display_dist(
  method = "density",
  center = TRUE,
  half_range = NULL,
  col = "black",
  rug = FALSE,
  palette = "Zissou 1",
  density_max = 3,
  bw = 0.2,
  scale_density = FALSE,
  ...
)

animate_dist(data, tour_path = grand_tour(1), ...)

Arguments

method	display method, histogram or density plot
center	should 1d projection be centered to have mean zero (default: TRUE). This pins the centre of distribution to the same place, and makes it easier to focus on the shape of the distribution.
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".
rug	draw rug plot showing position of actual data points?
palette	name of color palette for point colour, used by hcl.colors, default "Zissou 1"
density_max	allow control of the y range for density plot
bw	binwidth for histogram and density, between 0-1, default 0.2
scale_density	Height of density is scaled at each projection, default FALSE
...	other arguments passed on to animate
data	matrix, or data frame containing numeric columns
tour_path	tour path generator, defaults to 2d grand tour

Examples

animate_dist(flea[, 1:6])

# Change inputs, to color by group, fix y axis, change bin width
# and scale bar height or density at each projection
animate_dist(flea[, 1:6], col=flea$species, density_max=5)
animate_dist(flea[, 1:6], col=flea$species, density_max=5, bw=0.1)
animate_dist(flea[, 1:6], col=flea$species, scale_density=TRUE)

# When the distribution is not centred, it tends to wander around in a
# distracting manner
animate_dist(flea[, 1:6], center = FALSE)

# Alternatively, you can display the distribution with a histogram
animate_dist(flea[, 1:6], method = "hist")
