Error message in animation

[KiyohikoN]

I am beginner to create animation in R. The following script which copeid from your site was run. But error message was occured as below. Could you please tell me how to fixt it?

Get data:

library(gapminder)

Charge libraries:

library(ggplot2) library(gganimate)

Make a ggplot, but add frame=year: one image per year

ggplot(gapminder, aes(gdpPercap, lifeExp, size = pop, color = continent)) + geom_point() + scale_x_log10() + theme_bw() +

gganimate specific bits:

labs(title = 'Year: {frame_time}', x = 'GDP per capita', y = 'life expectancy') + transition_time(year) + ease_aes('linear')

Save at gif:

anim_save("271-ggplot2-animated-gif-chart-with-gganimate1.gif")

Error: The animation object does not specify a save_animation method Traceback:

1. anim_save("271-ggplot2-animated-gif-chart-with-gganimate1.gif", . animation = last_animation())
2. save_animation(animation, filename)
3. save_animation.default(animation, filename)
4. stop("The animation object does not specify a save_animation method", . call. = FALSE)

Hi @KiyohikoN ! Thanks for your message and sorry for the late reply!

I tried with gganimate 1.0.9 ggplot2 3.5.0 and gapminder 1.0.0, and everything works as expected (no error).

If possible, can you show the output of sessionInfo() when this error happens?
