tm_animate
Arguments
- by
group by variable used to create the animation frames. Note: it is called
pages
in the core functiontm_facets()
.- nframes
number of animation frames. So far, this only applied experimentally in transition map variables. See the extension package tmap.cartogram.
- fps
frames per second. Default: 30 for
tm_facets_animate
and 2 fortm_facets_animate_slow
.- play
how should the animation be played? One of
"loop"
(default),"pingpong"
, and"once"
, where"loop"
means that the animation will loop indefinitely,"pingpong"
means that it will play forward and then backward, and"once"
means that it will play only once.- dpr
device pixel ratio. The ratio between the physical pixel density of a device and its logical pixel density.

tm_facets()
Details
Specify an animation from a tmap plot. This is similar to creating facets with tm_facets()
. Instead of showing facets next to each other, they are shown as animation frames. The animation subsequently can be exported to a gif or video file (e.g. mp4) with tmap_animation()
. If the tmap plot with tm_animate()
is printed, the animation will be previewed. The default tm_animate()
will show the individual frames slowly (frame per seconds (fps) set to 2) whereas tm_animate_fast()
will show them like a movie (with a fps set to 24).
