error with loop=FALSE option about gganimate

[ottlngr]

To solve this and to disable looping, one has to set loop = 1 in ani.options(), so that -loop 1 is forwarded to ImageMagick. From the ImageMagick manual:

-loop {number}:Number of times the GIF animation is to cycle though the image sequence before stopping.

So this is actually not an issue with gganimate but rather with the animation package, which provides ani.options().

Is there a workaround for this issue?

This issue should be resurrected - all renderers default to loop=TRUE. If I define and use

altrenderer <- gifski_renderer(loop=FALSE)
anim_save(...etc..., renderer=altrenderer)

then I can get the desired result, but the conversation here all points towards using ani.options(loop=TRUE) to manage this.

One simple approach to this would be to have loop=TRUE in the signature in anim_save and then have the default renderer construction use the value of loop.

At the very least it's a documentation issue.

This issue is related to the old API and has no bearing on the new version.

[pearsonca]

Fair enough; what is the "right" way to do it in the new API?

[thomasp85]

Do it in the renderer as you are doing already. Not all types of output can be looped so it does not make sense to have an argument in animate()
