In spinifex: Manual Tours, Manual Control of Dynamic Projections of Numeric Multivariate Data

Animates the provided tour path.

Description

, see ggtour. Takes the result of tourr::save_history() or manual_tour(), interpolates over the path and renders into a specified render_type.

Usage

play_tour_path(
  tour_path,
  data = NULL,
  angle = 0.05,
  render_type = render_plotly,
  ...
)

Arguments

tour_path	The result of tourr::save_history() or manual_tour().
data	Optional, number of columns must match that of tour_path.
angle	Target distance (in radians) between steps. Defaults to .05.
render_type	Graphics to render to. Defaults to render_plotly, alternative use render_gganimate.
...	Optionally pass additional arguments to render_ and the function used in render_type.
