    #> [1] "numeric"

    x <- 1
    class(x)

    #Uppercase L should be suffixed with the number to assign integer datatype.
    x <- 1L

    #Both TRUE and T means logical True. It should be in uppercase as R is a case sensitive.

    class(x)
    #> [1] "logical"


    x <- T
    class(x)
    #> [1] "logical"

    x <- 'some text'
    class(x)
    #> [1] "character"

    x <- "Isn't it?"
    class(x)
    #> [1] "character"

    x <- 'She said, "It is great"'
    class(x)
    #> [1] "character"

    x <- 'She said, "It\'s great"'
    class(x)
    #> [1] "character"

    x <- "She said, \"Wow\""
    class(x)
    #> [1] "character"
