element_marquee makes element disappear

[alejandrohagan]

Hi,

I'm running the below example and for some reason the element disappears when I use element_marquee. If I use ggplot2::element_text() instead, the element reappears.

To be clear both geom_marquee() and element_marquee() do not work

Any thoughts?

session info is below

library(tidyverse)
library(marquee)




cars <- sub("(\\w+)", "{.red ***\\1***}", rownames(mtcars))


md_text <- 
  "# Lorem Ipsum

ggplot(mtcars) + aes(disp, mpg,label=cars) + 
  geom_marquee(size = 2) +
  ggtitle(md_text) + 
  theme(plot.title = element_marquee(size = 9))
```

My best guess is that you are using the default device which does not support the advanced text rendering required for marquee. Try to use the ragg devices instead

My guess is that the new version will fix this for you as it has fallback behaviour for older graphics devices. Feel free to reopen if that is not the case
