I installed gganimate packages from CRAN and run the sample codes provided:

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

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')

But got the following error:

Error in UseMethod("conditionCall") : no applicable method for 'conditionCall' applied to an object of class "NULL"

I've already installed magick, so could figure it our what's going on here. Any suggestions will be appreciated.

Try removing the facet_wrap first. I can't test though. – NelsonGon Feb 11 '19 at 16:05
Nope, still the same error, unfortunately. – user2236600 Feb 11 '19 at 16:10
This worked for me exactly as written; tested with `gganimate_0.9.9.9999` and `ggplot2_3.1.0` – MrFlick Feb 11 '19 at 17:34

Not sure why. But I've fixed it after I updated R to 3.5.2, previously it was 3.4.3. – user2236600 Feb 11 '19 at 18:37
