SplitToDummy: Split Strings of a Vector and Provide Dummy Codes for Found Pieces
Description
Split the strings of a character vector, put together all the unique pieces and return a matrix of dummy vectors for each single value.
Usage
SplitToDummy(x, split = ",", ...)
Value
a data.frame containing x and all the found dummy vectors
Arguments
x
character vector, each element of which is to be split. Other inputs, including a factor, will give an error.
split
character vector (or object which can be coerced to such) containing regular expression(s) (unless fixed = TRUE) to use for splitting. If empty matches occur, in particular if split has length 0, x is split into single characters. If split has length greater than 1, it is re-cycled along x.
