A function to convert a string, or vector of character codes, into a vector of characters.
This is a function I have found useful on several occasions. An example is counting successive sequences of characters in a string (eg, for run length encoding). A recent Community task was to count sequences of numbers in a vector, for which the function seqcount was created. Counting characters in a string can be done using char to convert a string to a vector of characters and then applying seqcount to that vector.
