animateOn: animateOn
In bobverity/bobFunctions: my personal functions

Description Usage Arguments

First of two functions needed to create mpg from static images. Run this function, then run the code needed to create a sequence of plots, then run animateOff(). Individual plots will be saved as jpg with a four-character number on the end (for example myFile0012.jpg), and can either be saved in the local directory or in a temporary directory. The animateOff() function should have the same shared arguments as animateOn() (for example the same fileName).

Note that this function requires ImageMagick to be installed, and has only been tested on Windows. If running for the first time you will likely need to add ImageMagick to the path using something like the following: Sys.setenv(PATH=paste(Sys.getenv("PATH"),"C:\Program Files\ImageMagick-6.9.3-Q16",sep=";"))
