maximum length of the resulting encodings, in characters
clean
if TRUE, return NA for unknown alphabetical characters
Value
the Roger Root encoded character vector
Details
The rogerroot function phentically encodes the given string
using the Roger Root algorithm. The variable word is a string
or vector of strings to encode.
The variable maxCodeLen is the limit on how long the returned
code should be. The default is 5.
The rogerroot algorithm is only defined for inputs over the
standard English alphabet, i.e., "A-Z.". Non-alphabetical
characters are removed from the string in a locale-dependent fashion.
This strips spaces, hyphens, and numbers. Other letters, such as
"<U+00DC>," may be permissible in the current locale but are unknown to
rogerroot. For inputs outside of its known range, the output
is undefined and NA is returned and a warning this
thrown. If clean is FALSE, rogerroot attempts
to process the strings. The default is TRUE.
