使用gganimate导出gif [英] Using gganimate to export gif

问题描述

包gganimate创建gif(来自此处的MWE代码):

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')

现在如何导出此gif?在gganimate的先前版本(现已存档)中，这很简单:

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

    gganimate(p, "output.gif")

但是，我在当前的gganimate程序包中找不到等效的函数.

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

注意:这个问题似乎与我从中获取MWE代码的问题完全相同.但是，gganimate已更新，并且在新版本中，在查看器窗格中显示动画与导出动画似乎是不同的问题.

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.

推荐答案

您可以这样做:

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