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.

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

It is in the gganimate package.
