r how to set x and y ranges in an animation video generated with saveVideo

Question

I make mpeg videos using the code below. r.mean is a spatRaster (the format for rasters in the terra package)

library(terra)
animation::saveVideo(animate(r.mean, n=1, pause = 0, sub = title_animate, col = rev(colorList), videoName_out))

I have included a screenshot of one frame of the animation. There is lots of white space above and below the actual image. I'd like to set the y range from -60 to 90. I've seen one example of use of saveVideo that looks like this with par parameters included in {}

saveVideo({
par(xxx, yy, zzz)}, 
some other stuff)

But I haven't had any luck making that work.

Answer 1

When asking an R question, please provide a minimal, self-contained, reproducible examples (as I do below).

Example data

library(terra)
r <- rast(nlyrs=3)
values(r) <- rep(1:3, ncell(r))

You can use the ani.height and ani.width arguments.

animation::saveGIF(animate(r, n=1), ani.height=200, ani.width=300)
