Error in build(..., self = self): “theme” argument is missing,

[dominicroye]

I have issues with animating several different plots with transition_states(). The error always indicate "theme" argument missing.

library(ggplot2)
library(gganimate)
library(dplyr)
library(lubridate)

set.seed(123)
data <- data.frame(
  date = seq.Date(from = as.Date("2023-01-01"), to = as.Date("2023-12-31"), by = "day"),
  city = rep(c("Madrid", "Barcelona", "Valencia"), each = 365),
  temperature = round(rnorm(365 * 3, mean = 15, sd = 10), 1),
  precipitation = round(runif(365 * 3, min = 0, max = 20), 1)
)

# Filtrar datos para dos ciudades y agrupar por mes

  filter(city %in% c("Madrid", "Barcelona")) %>%
  mutate(month = floor_date(date, "month")) %>%
  group_by(city, month) %>%
  summarize(
    avg_temp = mean(temperature),
    total_precip = sum(precipitation)
  )

There seems to be a bug. This example has similar issues.
