Getting Help
Learning a new software is like learning a new language, and some functions or commands will be like unknown words. An important function in R is help. For example, if we wanted to know how exactly to use the sum function, we could type help(sum). You will see the results in the bottom-right panel.
help(sum)
or by using the question mark sign (?)
?sum
