Fixing the attempt to apply non-function Error in gganimate's transition_states

Hey there, that error you're seeing with transition_states is super common when there's a version mismatch between gganimate and ggplot2—let's walk through how to fix it step by step.

1. First, check your current package versions

Run these commands to see what versions you have installed:

packageVersion("gganimate")
packageVersion("ggplot2")

gganimate relies heavily on ggplot2's internal structure, and major version changes in either can break compatibility. For example, older versions of gganimate (pre-1.0) don't play nicely with ggplot2 3.4+.

2. Reinstall compatible versions

The most reliable fix is to get the latest stable versions that work together:

First, remove the existing packages (make sure to restart your R session after this):
```
remove.packages(c("gganimate", "ggplot2"))
```

Then install the latest CRAN versions:

install.packages(c("ggplot2", "gganimate"))

If the latest versions still cause issues, you can try installing a specific stable pair—like gganimate 1.0.8 with ggplot2 3.4.4 (this combination is widely tested):

install.packages("ggplot2", version = "3.4.4")
install.packages("gganimate", version = "1.0.8")

3. Restart R and re-run your code

After reinstalling, restart your entire R session (don't just detach packages!) and run your code again with the packages loaded properly:

library(ggplot2)
library(gganimate)

p <- ggplot(iris, aes(x = Petal.Width, y = Petal.Length)) + 
  geom_point()

p + transition_states(Species, transition_length = 2, state_length = 1)
