Learning objectives
• Understand the concept of strings and rules for defining them in R
• Use escapes to include special characters like quotes within strings
• Employ {stringr} functions to format strings:
• Change case with str_to_lower(), str_to_upper(), str_to_title()
• Trim whitespace with str_trim() and str_squish()
• Pad strings to equal width with str_pad()
• Wrap text to a certain width using str_wrap()
• Split strings into parts using str_split() and separate()
• Combine strings together with paste() and paste0()
• Extract substrings from strings using str_sub()
