cc.RdSplit strings by comma into character vector(s)
cc(x, simplify)
| x | Vector of comma separated character strings |
|---|---|
| simplify | Logical indicating whether to return a character vector (the default) when the length of x is one. This argument does nothing if the length of x is greater than 1. |
If length of x is 1 then a character vector otherwise a list of character vectors.
