Animate a data cube as an image time series

Description

Animate a data cube as an image time series

Usage

animate(
  x,
  ...,
  fps = 1,
  loop = 0,
  width = dev.size(units = "px")[1],
  height = dev.size(units = "px")[2],
  save_as = NULL,
  plot = TRUE
)

Arguments

x

a data cube proxy object (class cube)

...

parameters passed to plot.cube

fps

frames per second of the animation

loop

how many iterations, 0 = infinite

width

width (in pixels) of the animation

height

height (in pixels) of the animation

save_as

character path where the animation shall be stored as a gif file

plot

logical; plot the animation (default is TRUE)

Details

Animations can be created for single band data cubes or RGB plots of multi-band data cubes (by providing the argument rgb) only.
