Error in the first example. #8

Here is the error message.

Error in transform_path(all_frames, next_state, ease, params$transition_length[i], : transformr is required to tween paths and lines

I find the cause of this bug is the function transition_states from gganimate.
However, I don;t use av and gganimate package before and don't know how to go deeper.

I run this code and fail both on Mac and on Win.
Here are my error message and session information.

av_renderer <- function(vfilter = "null", filename = 'output.mp4'){
  function(frames, fps){
    unlink(filename)
    av::av_encode_video(frames, filename, framerate = fps, vfilter = vfilter)
  }
}

# Create the gganimate plot
p <- ggplot(airquality, aes(Day, Temp)) + 
  geom_line(size = 2, colour = 'steelblue') + 
  transition_states(Month, 4, 1) + 
  shadow_mark(size = 1, colour = 'grey')

Anyone working on an implmentation of av_renderer? Why was it removed?

jeroen · 2023-05-26T14:14:58Z

It is in the gganimate package. Op vr 26 mei 2023 15:49 schreef Fredrik Karlsson ***@***.***>:
