R Escape Characters
To insert characters that are illegal in a string, you must use an escape character.
An escape character is a backslash
\ followed by the character you want to insert.
An example of an illegal character is a double quote inside a string that is surrounded by double quotes:
Error: unexpected symbol in "str <- "We are the so-called "Vikings"
To fix this problem, use the escape character
The escape character allows you to use double quotes when you normally would not be allowed:
Note that auto-printing the str variable will print the backslash
in the output. You can use the
cat() function to print
it without backslash.
