Render frames of animation to a gif file

render_gif(
  data,
  tour_path,
  display,
  gif_file = "animation.gif",
  ...,
  apf = 1/10,
  frames = 50,
  rescale = FALSE,
  sphere = FALSE,
  start = NULL,
  loop = TRUE
)

Arguments

data: matrix, or data frame containing numeric columns
tour_path: tour path generator
display: the method used to render the projected data, e.g. display_xy, display_pcp
gif_file: Name of gif file (default = "animation.gif")
...: other options passed to png
apf: angle (in radians) per frame
frames: number of frames in output
rescale: default FALSE. If TRUE, rescale all variables to range [0,1]
sphere: if true, sphere all variables
start: starting projection. If NULL, uses path default.

Examples

if (FALSE) {
# gifski needs to be installed to render a gif
if (requireNamespace("gifski", quietly = TRUE)) {
  gif_file <- file.path(tempdir(), "test.gif")
  render_gif(flea[, 1:6], grand_tour(), display_xy(), gif_file)
  utils::browseURL(gif_file)
  unlink(gif_file)
}
