Animation files not saved #93

I am able to create animations in RStudio, but they are only displayed in the Viewer window.
I do not find any files containing the animation so I could use them outside of RStudio.
How can I "catch" the output file.
Also,
plot does work for my configuration (RStudio 1.2.805, R 3.5.1 MacOS 10.13.6)

Here is my example

library(ggplot2)
library(gapminder)
library(gganimate)

ggplot(gapminder, aes(gdpPercap, lifeExp, size = pop, colour = country)) +
  geom_point(alpha = 0.7, show.legend = FALSE) +
  scale_colour_manual(values = country_colors) +
  scale_size(range = c(2, 12)) +
  scale_x_log10() +
  facet_wrap(~continent) +
  # Here comes the gganimate specific bits
  labs(title = 'Year: {frame_time}', x = 'GDP per capita', y = 'life expectancy') +
  transition_time(year) +
  ease_aes('linear') -> p
animate(p,device="png")

and here is what I see when I try plot:

plot(p)
Error in UseMethod("ggplot_gtable") :
no applicable method for 'ggplot_gtable' applied to an object of class "gganim_built"

The default is to return a magick object which can be saved with image_write()

The plot method is currently down due to some patchwork issues

Thank you. Perhaps that is worth mentioning in the README.

Thank you both for this, but the returned object doesn't seem to be a magick object so I'm unable to save your example plot using image_write:

library(ggplot2)
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')

#> Disabled features: fftw, ghostscript, x11

image_write(p, 'test.gif')
#> Error: The 'image' argument is not a magick image object.

I had missed out the animate stage. For anyone visiting this issue, the following should work:

library(ggplot2)
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')

image <- animate(p)

library(magick)
#> Linking to ImageMagick 6.9.9.39
#> Enabled features: cairo, fontconfig, freetype, lcms, pango, rsvg, webp
#> Disabled features: fftw, ghostscript, x11
image_write(image, 'test.gif')

@thomasp85 Would you like me to add an example of saving an image file to the README?

@thomasp85

I'll do it - I still haven't finalised how this should work out in the end, e.g. if an equivalent of ggsave() should be provided

@gregrs-uk

Sure, no problem. Thanks.

Hi all, I am working on embedding animated gif into html report (though rendering .Rmd) and ran into the same issues as @gregrs-uk when saving image into .gif

image_write(image, 'test.gif')
Error: The 'image' argument is not a magick image object.
@thomasp85 , has anything changes since a month ago?
Thank you!

There shouldn’t be any need for additional steps when embedding animations with rmarkdown. Just treat it like a regular ggplot

Thanks, Thomas, it worked 🥇
After killing half of the day trying to come up with complicated solution, turned out that the simplicity is the genius! My html report looks beautiful with the animated viz! Janssen R&D is getting such a makeover thanks to all the wonderful work you are doing!

Just for any confused Linux people out there, I get the

#> Error: The 'image' argument is not a magick image object.

error message with Ubuntu 16.04 but not with 17.10, I presume because of an older version of ImageMagick. I'm guessing to get it running on 16.04 you'll have to find another repository or compile from source. I haven't done this myself so I can't be sure.

@thomasp85

gganimate does not use ImageMagick in any way. It has changed default renderer to gifski which is why image_write no longer works and the returned object. anim_save() will always work no matter the renderer

Aha. Apologies. I'll do that then. Thanks 😀
