The Caverphone family of phonetic algorithms
string or vector of strings to encode
maximum length of the resulting encodings, in characters
maxCodeLen is the limit on how long the returned
Caverphone code should be. The default is 6, unless
is set to
TRUE, then the default is 10.
caverphone to use the
Caverphone2 method, instead of the original.
caverphone 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
caverphone. For inputs outside of its known range, the output is
NA is returned and a
warning this thrown.
caverphone attempts to process the
strings. The default is
the Caverphone encoded character vector
