I have run animations in the past up to 2 weeks ago on Windows 7, R 3.0.1. Today I loaded R 3.0.2 and needed to download the animations package to run make an animation. After doing so when I try to run the animation (here is a script) I get the following error:
> saveGIF(FUN2(), interval = 0.1, outdir = "images/animate")
I cannot find ImageMagick with convert = "convert"
NULL
Warning messages:
1: running command 'convert --version' had status 4
2: In im.convert(img.files, output = movie.name, convert = convert, :
ImageMagick not installed yet!
I have ImageMagick installed and on the path as demonstrated in the video I made of the problem: http://www.youtube.com/watch?v=gvpawqLyCZY&feature=youtu.be
I can run convert --version in the Windows command line and get the following:
C:\Users\trinker>convert --version

Yet running system("convert --version") in R yields:
Invalid drive specification.

What am I doing wrong or might I alter to make the animation package (and R) see ImageMagick?
Here is additional information for the problem (in the R command line I get):
> system("convert -version")
Invalid drive specification.
