Parameter no valid

[Juanjolizard]

Good afternoom,
When I try to produce a gif based on different rasters and levelplot. The last parameter convert_extra returns one error.
Parameter no valid : -loop. I'm using the default option. Could you share an example using this function?
Thanks in advance.

You haven't provided a working example which makes it nearly impossible for me to provide assistance. The following example works without issue on my machine. The image created is animated.

library(raster)
#> Loading required package: sp
library(dismotools)

fn <- system.file("external/test.grd", package="raster")
s <- raster(fn)
s <- stack(s, s*2, s*3 , s*4, s*5)

ok <- animate_gif(s)
#> converting to  animation.gif
