Is there a way to have animations appear in a .Rmd source window?

[arthur.t]

I'm using gganimate for my animations with RStudio v 1.1.463.

My animations appear in the "Viewer" window instead of below the code chunk. When I read gganimate documentation, I get the impression there's a way to have the animations appear in the source window.

For example, this chunk creates an image in the Viewer.

library(ggplot2)
library(gganimate)

ggplot(iris) +
  aes(Petal.Width, Petal.Length) +
  geom_point() +
  transition_states(Species,
                    transition_length = 2,
                    state_length = 1)

On >= 1.2 versions of Rstudio, you can embed animations into .Rmd files if your render it as .mp4 (I can't tell if that is also the case with your version).

```{r, warning=FALSE, message=FALSE}
ibrary(ggplot2)
library(gganimate)

p <- ggplot(iris) +
  aes(Petal.Width, Petal.Length) +
  geom_point() +
  transition_states(Species,
                    transition_length = 2,
                    state_length = 1)
animate(p, renderer = ffmpeg_renderer(format = "webm"))
```

Thanks! I tested and it works.

Is there a way to hide the output text? It writes this to my source window.

I tried suppressMessages() and invisble() but neither worked.

That is weird, I didn't get any of that when running the chunk, try putting this in your chunks header

```{r, warning=FALSE, message=FALSE}
