# MAKE FRIENDS WITH R
# BASED ON MAKE FRIENDS WITH R BY JONATHAN TEMPLIN
# CREATED BY JIHONG ZHANG
# R comments begin with a # -- there are no multiline comments
# RStudio helps you build syntax
# GREEN: Comments and character values in single or double quotes
# You can use the tab key to complete object names, functions, and arugments
# R is case sensitive. That means R and r are two different things.
