I am trying to create an animation or GIF that shows the evolution of an environmental condition over time. Basically, I have a dataset (example below) with year, value of the environmental condition, unit, and coordinates.

Complete dataset:

You can create a series of png files and assemble them into an animation with the gifski package:

library(ggplot2)
library(gifski)

for(i in 1:30){
  gg <- ggplot(......)
  ggsave(sprintf("myplotd.png", i), gg)
}

png_files <- Sys.glob("myplot*.png")

gifski(
  png_files,
  "myanimation.gif",
  width = 400, height = 400,
  delay = 1/5 # 5 images per second
)

file.remove(png_files)
