Instruction

All right. In data analysis, you not only deal with numbers but also with text values called strings. Strings can represent names, descriptions, properties, and so on. In R, strings can be surrounded with single quotation marks (') or double quotation marks ("), like this: 

'John'
or 
"John"

Exercise

Type your name into R. Don't forget to surround it with quotation marks.
