“R” The print statement is optional once in a while, the first index of an array is one instead of zero.
I don’t think it’s really necessary to have three years of experience using “R” because three years of experience with any other language will give you the same results. If it this language use it, else use the other language 🙂
My point is, if your vocabulary is good in one language your vocabulary will probably be good in another language. Syntax is our grammar rules. In this day and age of auto complete and code completion it is really easy to code in multiple languages.
