In my previous post I showed an animation of Arctic Sea Ice Extent from the 1980′s through August, 2012 (link). In this post, I show how to build this Arctic Sea ice Extent animated chart.
To develop my animation of the daily Arctic Sea Ice extent, I decided to produce a plot for each year that showed the current year in red and the previous years in grey. I go this idea from Tamino at Open Mind.
Here is my R script: link.
Once I have the individual png files for each year, I use Photoshop Elements to generate my animation.
After getting Pierre’s comment about using the animation package, I gave it another try. The 2nd time, I got it to work with ease.
I can now update the daily ASIE plot automatically without any Photoshop Elements involvement.
