transition_reveal() -- Error: Expected single logical value

[edornshuld]

The transition_reveal() function results in an error in an Rmd file: Error: Expected single logical value

Using the example from the docs:

library(ggplot2)
library(gganimate)

anim <- ggplot(airquality, aes(Day, Temp, group = Month)) +
  geom_line() +
  transition_reveal(Day)

anim

[thomasp85]

this has been fixed in the dev version of tweenr

[dafealos]

I have the same error, How can I fix it? which function of tweenr?

[pelegr]

I've also encountered this on a machine running ubuntu 18.04 and the latest R.
The same code is running just fine on my windows based laptop.

Would really appreciate it if someone could point out what package / exact versions are affected,
and how to workaround the issue.

Update:
Ended up using remotes to install tweenr 2.0.1 (was on 2.0.0 previously).
The error seems to go away but now it seems to crash in the process with no error given.
I ended up reverting back to tweenr 1.0.2, and the animation successfully renders then.
