Provides the Roger Root name coding system
string or vector of strings to encode
maximum length of the resulting encodings, in characters
rogerroot function phentically encodes the given string
using the Roger Root algorithm. The variable
word is a string
or vector of strings to encode.
maxCodeLen is the limit on how long the returned
code should be. The default is 5.
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
"Ü," 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
to process the strings. The default is
the Roger Root encoded character vector
