Create gif from series of png files

Hi,

I have many png files that I would like to stitch together, in order to
make a gif file.

Any ideas how I would do this?

ImageMagick is good for this.  The magick package in R makes most (all?) 
of its features available.  The image_animate() function can produce an 
animation; see either the ImageMagick docs online, or the "intro" 
vignette in the magick package for examples and instructions.
