[R] Help needed on "switch" function

[Joris Meys]

R is confused about the type in the switch, reads it as numeric
instead of a character. Try :
              temp1.name <- switch(temp1,
                                  "1" = "aa",
                                  "2" = "bb",
                                  "3" = "cc",
                                  "4" = "dd",
                                  "5" = "ee")
> temp1.name
[1] "aa"

cheers
