Interface to phonetic coding functions.
pho_h(str)
soundex(str)A character vector or matrix. Factors are converted to character.
Translates its argument to a phonetic code. pho_h
by J<U+001B29FD>Joerg Michael (see references) is intended for German language
and normalizes umlauts and accent characters.
soundex is a widespread algorithm for English names. This implementation
can only handle common characters. Both algorithms strip off
non-alphabetical characters, with the exception that numbers are left
unchanged by pho_h.
The C code for soundex was taken from PostgreSQL 8.3.6.
A character vector or matrix with the same size and dimensions as str,
containing its phonetic encoding.
