I\'m trying to use imagemagick to create a simple .gif file from a few png files, using the general approach outlined here: http://www.r-bloggers.com/animated-plots-with-r/<
You probably installed ImageMagick 7.X on your machine. This version no longer includes convert.exe and the error that you are receiving is from the convert command of Windows. You can use magick.exe instead or select Install legacy utilities (e.g. convert) during the installation to install convert.exe on your machine..
