R Strings

R Strings

Single quotes or double quotes are used to represent Strings in R programming language. We shall learn rules to write a String, embed special characters in it, and some of the common operations like concatenation of two strings, finding length of string, etc.

Rules to write R Strings

Following are the rules to write a valid string in R programming language :

  • Either single quotes or double quotes should be used to enclose a string value.
    str1 = Hello
    str2 = Hello
  • As only single quote or double quotes are the special characters used to represent an R string, to include them in a String requires special care.
  • To include a single quote inside a string value, surround the single quote with double quotes.
    For Who’s hello is that?
    str1 = “Who”“s hello is that?”
  • To include a double quote inside a string value, surround the double quote with single quotes.
    For R says, “Hello”.
    str1 = “R says, ‘‘Hello’‘.”
  • Single quote or double quote could be included at the starting or ending of the string value as is.
    For ‘Hello.”
    str = “Hello.
