Description Usage Arguments Value Note Author(s) References See Also Examples

This function takes a letter string (e.g. ABD) and converts to binary encoding (e.g. 1101).

1 2	letter_string_to_binary(letter_string, letter_codes_in_desired_order = "alphabet")

`letter_string`	A string of letters (e.g. "ABD")
`letter_codes_in_desired_order`	The letter codes in the desired order. The default keyword, "alphabet", uses the standard 26 capital letters; the output binary codes will thus have 26 positions. If the user inputs fewer letters here, or puts them in another order, those will be used.

numcodes A list with the binary codes.

Go BEARS!
