You need to read the "An Introduction to R" manual which was probably installed when you installed R on your un-named OS (Windows, I take it).  You probably also want to read the posting-guide referenced at the bottom of the email.  But to get you started, you need to load a package before using it.  In your case 

library(yags) 

should get you started.  Hope this is helpful,
