Setting the initial view of a motion chart in R

Following on from my article about accessing and plotting World Bank data with R I want to talk about how to change the initial view of a motion chart. Over the last couple of weeks I have been asked a view times how to do this. For instance Stephen O’Grady wanted to create a motion chart, which shows initially a line chart, rather than a bubble chart. Changing the initial settings of a motion chart is actually quite easy, if you know how to.
