Using gganimate to export gif

问题:

The package gganimate creates gifs (MWE code from here):

    library(ggplot2)
    #devtools::install_github('thomasp85/gganimate')
    library(gganimate)

    p <- ggplot(mtcars, aes(factor(cyl), mpg)) + 
            geom_boxplot() + 
            # Here comes the gganimate code
            transition_states(
                    gear,
                    transition_length = 2,
                    state_length = 1
            ) +
            enter_fade() + 
            exit_shrink() +
            ease_aes('sine-in-out')

How can export this gif now? In the previous (now archived) version of gganimate this was simple:

    gganimate(p, "output.gif")

However, I could not find an equivalent function in the current gganimate package.

Note: This question seems like an exact duplicated of the question from which I took the code for the MWE. However, gganimate has been updated and in the new version, displaying an animation in the viewer pane vs. exporting it seem to be different issues.

回答1:

You can do like this:

anim <- animate(p)
magick::image_write(anim, path="myanimation.gif")
