2015 was a good year for pirate booty - your ship collected 100,000 gold coins. Create an object called and assign the correct value to it.
gold.in.2015<-100800
Oops, during the last inspection we discovered that one of your pirates Skippy McGee hid 800 gold coins in his underwear. Go ahead and add those gold coins to the object gold.in.2015. Next, create an object called plank.list with the name of the pirate thief.
